I am trying to get a substring out of certain string. like below:
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc -I. -I./ --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -DPIC -DHAVE_AV_CONFIG_H -arch armv7 --sysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -mcpu=cortex-a8 -fPIC -g -MMD -MF libavcodec/arm/ac3dsp_armv6.d -MT - -c -o - libavcodec/arm/ac3dsp_armv6.S -E
I want to get string ac3dsp_armv6.S out, how to do it using Perl?
my $string = '/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc -I. -I./ --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -DPIC -DHAVE_AV_CONFIG_H -arch armv7 --sysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -mcpu=cortex-a8 -fPIC -g -MMD -MF libavcodec/arm/ac3dsp_armv6.d -MT - -c -o - libavcodec/arm/ac3dsp_armv6.S -E';
my #r = split(/ / ,( split /\//, $string )[-1]);
print $r[0];
One possible approach.
my $string = '/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc -I. -I./ --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -DPIC -DHAVE_AV_CONFIG_H -arch armv7 --sysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -mcpu=cortex-a8 -fPIC -g -MMD -MF libavcodec/arm/ac3dsp_armv6.d -MT - -c -o - libavcodec/arm/ac3dsp_armv6.S -E'
my ($result)=$string=~m#/(.+?)\s+\-E\s*\z#gis;
print $result;
It is hard to answer this question as there is not enough information to go by. There are plenty of ways to extract the string that are not guaranteed to be generic.
Is the string coming as fixed-width format? Probably not.
What is so unique about the sought-after substring that one could use to extract it?
Have you considered using regular expressions?
perldoc perlrequick and perldoc perlretut should provide the required know-how to achieve the stated objective.

I'm working with STM32CubeIDE using gcc compiler. In the build output I have to search for warnings and errors in a hundred lines of compiler-output infos. I'm explicitly interested in all warnings and errors! But I do not need something like this as there isn't any warning or error:

How can I get rid of this crap ?
I searched for gcc option help files and some "how to increase verbosity" hoping to find the contrary ;-) .
I found explicit help for reducing warnings, which is not my intention.
I've written a program of the following form:
#include "stuff_I_need.h"
int main(){
construct_array(); // uses OpenMP pragma's
print_array();
return(0);
}
that compiles, links, and runs correctly with the following command:
`gcc44 -I/home/matteson/sundials/include/ main.c -lm -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial -fopenmp -o /home/matteson/MPI_test/CVODE_test/main_test`
"gcc44" is simply gcc version 4.4 and is named like this because it's being compiled on a cluster that maintains several versions of gcc. The libraries sundials_cvode and sundials_nvecserial are used in the solving of several differential equations during the construction of the array.
Now when I want to transfer over to Matlab and try to compile the mex file of the form:
#include "stuff_I_need.h"
void mexFunction(int nlhs,mxArray* plhs[], int nrhs, const mxArray* prhs[]){
construct_array(); // uses OpenMP pragma's
print_array();
}
and try to compile with the following command in Matlab:
>> mex -v CC="gcc44" CFLAGS="\$CFLAGS -I/home/matteson/sundials/include/ -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial" mex_cvode.c
I get the following messages culminating in a link error:

Somehow, I'm not giving the correct flags to link appropriately. As I get the same set of errors (plus a few more) if I remove the commands to link in the gcc44 command, I'm pretty sure that I'm not getting the compiler to "see" the libraries.
My questions are :
If my analysis of the error is correct, what flags do I need to pass to the mex compilation command to successfully link?
Alternatively, what are the gcc flags to compile and link outside of the Matlab environment to compile a .mex64 executable?
If my analysis is wrong, where to go from here?
I think I've ruled out the unsupported compiler warning since I've been able to compile simple mex with OpenMP programs using gcc 4.4, but these did not have to link against anything except the math library. Also, if I compile with version gcc version 4.1.2 or 4.3.4 with or without the "-fopenmp" flags I get the same error.
In the end I do need version 4.4 because of certain OpenMP support that did not appear in prior versions.
Thanks in advance for the help.

So I tried the command with the statements outside the the quotes, and got the error:

I'm a bit confused about the suggestion to recompile with "-fPIC" because when I look at the gcc44 command I see the -fPIC as an option.
Are they saying to recompile the library with -fPIC?
I don't have the source for the library, if the suggestion is to recompile the library is there a workaround?
What does "relocation against local object" mean?
My continued thanks.
Try not putting the -l, -L, or -I arguments in those environment variables. The mex function will handle those types of arguments directly. So perhaps something like:
mex -v CC="gcc44" CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp" -I/home/matteson/sundials/include/ -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial mex_cvode.c
Kwatford put me on the right track with the second question. I was able to get the mex command to work by rebuilding the sundials solver with shared libraries. Specifically, I built with:
% make distclean
% ./configure --prefix=/home/matteson/sundials --enable-shared
% make
% make install
Also, thanks to kwatford for the fix to the original by calling:
mex -v CC="gcc44" CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp" -I/home/matteson/sundials/include/ -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial mex_cvode.c
since mex knows how to handle the -L and -I.
Matlab uses its own libstdc and libstdc++.
The shortcut would be to do a symbolink to those libraries to the gcc44 libraries that you want to use.
But this may not be the desired way to go. You could try compiling outside matlab prompt and see if it still fails compilation first.
What I want to do is connecting and retrieving data from oracle database through perl.

Sounds like an issue with SELinux. Try disabling it and see if this resolves your problem:

I do not know what you are missing and where you are going wrong. But I always follow below method and it has worked 100% times for me. Try this method and if it does not work, then I can definitely make it work for you....
One thing I notice in your post is that you are getting permissions issues. Try running these steps as root.

DONE !!!
I am currently trying to build an iPhone app that I have developed using the iPhone toolchain. When I finished creating the makefile it was giving me this error when it tried to load my .o files together:
/bin/sh: -c: line 0: unexpected EOF while looking for matching `"'
/bin/sh: -c: line 1: syntax error: unexpected end of file
Upon looking at the shell code it was trying to execute, I determined that it dropped the last quote so I made a quick fix to my makefile. Upon loading, it gave me the following error:
Undefined symbols:
"_main", referenced from:
__start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** ["Autotune] Error 1
If I read this correctly it cannot find my main function, but it is clearly defined in main.mm. I would like to keep my project closed source, but I am willing to show certain, non-vital parts of my code. I don't see why it is not compiling; it worked fine on Xcode. Did my change to the Makefile somehow cause it to not load the _main symbol? How can I fix this problem? I am quite stumped.
Here is my Makefile:

#echo "Application $(INSTALLFOLDER) installed"
clean:
#rm -f $(SRCDIR)/*.o
#rm -rf $(BUILDDIR)
#rm -f $(PROJECTNAME)
It is important to note that Prefix.h used to be a precompiled header but I just changed it to a header file and told make to include it in all my source files.
The quick fix that I made for the problem of not including the final quote was:
changing:
$(PROJECTNAME): $(OBJS)
$(LD) $(LDFLAGS) -o $# $^
to:
$(PROJECTNAME): $(OBJS)
$(LD) $(LDFLAGS) -o $# $^"
To restate my question after that long post. Did my change to the Makefile somehow cause it to not load the _main symbol?
I figured it out my actual app name given by PROJECTNAME had a space in it. I removed the space my quick fix and changed LD from apple-arm-darwin9-gcc to apple-arm-darwin9-g++. after that it worked.
I've written a program of the following form:
#include "stuff_I_need.h"
int main(){
construct_array(); // uses OpenMP pragma's
print_array();
return(0);
}
that compiles, links, and runs correctly with the following command:
`gcc44 -I/home/matteson/sundials/include/ main.c -lm -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial -fopenmp -o /home/matteson/MPI_test/CVODE_test/main_test`
"gcc44" is simply gcc version 4.4 and is named like this because it's being compiled on a cluster that maintains several versions of gcc. The libraries sundials_cvode and sundials_nvecserial are used in the solving of several differential equations during the construction of the array.
Now when I want to transfer over to Matlab and try to compile the mex file of the form:
#include "stuff_I_need.h"
void mexFunction(int nlhs,mxArray* plhs[], int nrhs, const mxArray* prhs[]){
construct_array(); // uses OpenMP pragma's
print_array();
}
and try to compile with the following command in Matlab:
>> mex -v CC="gcc44" CFLAGS="\$CFLAGS -I/home/matteson/sundials/include/ -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial" mex_cvode.c
I get the following messages culminating in a link error:

Somehow, I'm not giving the correct flags to link appropriately. As I get the same set of errors (plus a few more) if I remove the commands to link in the gcc44 command, I'm pretty sure that I'm not getting the compiler to "see" the libraries.
My questions are :
If my analysis of the error is correct, what flags do I need to pass to the mex compilation command to successfully link?
Alternatively, what are the gcc flags to compile and link outside of the Matlab environment to compile a .mex64 executable?
If my analysis is wrong, where to go from here?
I think I've ruled out the unsupported compiler warning since I've been able to compile simple mex with OpenMP programs using gcc 4.4, but these did not have to link against anything except the math library. Also, if I compile with version gcc version 4.1.2 or 4.3.4 with or without the "-fopenmp" flags I get the same error.
In the end I do need version 4.4 because of certain OpenMP support that did not appear in prior versions.
Thanks in advance for the help.

So I tried the command with the statements outside the the quotes, and got the error:

I'm a bit confused about the suggestion to recompile with "-fPIC" because when I look at the gcc44 command I see the -fPIC as an option.
Are they saying to recompile the library with -fPIC?
I don't have the source for the library, if the suggestion is to recompile the library is there a workaround?
What does "relocation against local object" mean?
My continued thanks.
Try not putting the -l, -L, or -I arguments in those environment variables. The mex function will handle those types of arguments directly. So perhaps something like:
mex -v CC="gcc44" CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp" -I/home/matteson/sundials/include/ -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial mex_cvode.c
Kwatford put me on the right track with the second question. I was able to get the mex command to work by rebuilding the sundials solver with shared libraries. Specifically, I built with:
% make distclean
% ./configure --prefix=/home/matteson/sundials --enable-shared
% make
% make install
Also, thanks to kwatford for the fix to the original by calling:
mex -v CC="gcc44" CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp" -I/home/matteson/sundials/include/ -L/home/matteson/sundials/lib -lsundials_cvode -lsundials_nvecserial mex_cvode.c
since mex knows how to handle the -L and -I.
Matlab uses its own libstdc and libstdc++.
The shortcut would be to do a symbolink to those libraries to the gcc44 libraries that you want to use.
But this may not be the desired way to go. You could try compiling outside matlab prompt and see if it still fails compilation first.
