I've been wanting to get my hands dirty with Opa, but had been really feeling the lack of a REPL, which is my weapon of choice in coming to terms with a new language. Lo and behold, the Opa Blog mentioned a tool called opatop which appeared to be just that, but it doesn't seem to be included the standard Mac or Ubuntu distributions.
I trekked over to GitHub, grabbed the source, and started building, but I'm getting the same error mentioned here:
+ /opt/local/bin/ocamlopt.opt dynlink.cmxa unix.cmxa str.cmxa nums.cmxa -g threads.cmxa -thread -I +zip zip.cmxa -I +ocamlgraph graph.cmxa -I /opt/local/lib/ocaml/ulex ulexing.cmxa buildinfos.cmxa libbase.cmxa compilerlib.cmxa libtrx.cmxa opacapi.cmxa passlib.cmxa libqmlcompil.cmxa jslang.cmxa ocamllang.cmxa libbsl.cmxa libbsl/bslregister.cmx opalang.cmxa -o libbsl/bslregister.native
File "_none_", line 1, characters 0-1:
Error: Cannot find file dynlink.cmxa
Command exited with code 2.
I know next to nothing about OCaml development, but it looks like other files with the same extension in the relevant library directory are "OCaml native library files". Given that, is this just a library that wasn't included in the OCaml distribution I ended up with? The Mantis bug referenced in the link above makes it look as though there may be conflicting assumptions about build environments at work.
Regardless, can anyone offer any advice?
Thanks!
OCaml isn't built with native dynlink for Lion yet, so dynlink.cmxa doesn't exist under the default install.
The following patch will enable allow you to build it. From within the OCaml src dir, patch -p1 < PATH/TO/PATCH, and reinstall OCaml as appropriate.
This is for OCaml 3.12.1

I have investigated Opa build under OS X Lion and have pushed 2 patches on opalang waiting for approval to solve main problems.
So when the patches will be available, this is my steps (as i remember) to make Opa work under Lion :
First, install necessary tools :
Install OS X Lion
Install Xcode 4
Install MacPorts
Install wget (macports)
Install coreutils (macports)
Install md5sha1sum (macports)
(I think that's all...)
Then compile Opa from source :
git clone https://github.com/MLstate/opalang.git
cd opalang
dependencies/installation_helper.sh --prefix ~/Opa
change your PATH in your ~/.profile : export PATH=~/Opa/bin:$PATH
re-source your .bashrc : source ~/.profile
./configure -prefix ~/Opa
make all install
Your new opa compiler should be in ~/Opa/bin :)

I can't get VS Code to play nice with WxWidgets on Linux or MacOS. It seems like it's trying to default to MSW and gives an error (detailed below)
The specific question is about VSCode (autocomplete, don't give false errors) with WxWidgets. In command prompt, compiling any Wx project works perfect.
Steps:
VS Code is installed
-Create folder for project. Let's call it /src/hello
-Create a hello.cpp file with code from: https://docs.wxwidgets.org/3.0/overview_helloworld.html
-Download WxWidgets into /src/hello/deps
-Going through steps to compile and install Wx https://docs.wxwidgets.org/trunk/plat_osx_install.html
-Check my Intellisense includes to include ${workspaceFolder}/**
-Now, in the command prompt, if I run:
g++ hello.cpp 'wx-config --cxxflags --libs' -o hello
./hello runs perfect!
But in VSCode is unusable because it's giving me this error:
cannot open source file "../../../lib/vc_lib/msw/wx/setup.h" (dependency of "wx/wxprec.h")
I'm pretty sure msw is for windows?
I feel like I've tried everything:
-Downloaded and Git version of Wx (Yeah, I know it's the same. But people on the wx forums recommended trying...)
-Use the Homebrew WxWidgets install.
-Using the sample projects included with Wx.
-Using the Hello World
-Same issues in Linux and MacOS.
-Updating Intellisense's includes every way you can think of.
-Using the output of wxconfig and putting the cxxflags and lib include output into Intellisense.
Is anyone able to use VS Code on Linux or MacOS with the Hello World Wx example? If so what are your intellisense settings?
My properties:
I'd rather not use Cmake for this.
I am building Swift compiler from source on CentOS 6, and am running into a library issue. After fighting with the build script for a while I have got where running ./utils/build-script eventually gives:

I just don't know how to tell the build system where to look. I have tried the usual CMAKE_LIBRARY_PATH (exporting on the command line - I am not sure if cmake works like the way LD_LIBRARY_PATH, LIBRARY_PATH work) but it can't seem to find it.
I also don't have root on the machine.
I had not tried building from source on CentOS 6 until I saw this question, but I have been able to build Swift 2.2 on CentOS 7.1 and Ubuntu 14.04, with partial success. A few things to think about:
You will need numerous dependencies required to build Swift, and unless
they happen to be already on the system, you will need root access to
install them.
Use -R flag with the build-script to create a release build.
Building in DebugAssert (the default) will require a lot of memory. In my case even 14 GB was not sufficient. A release build
can be done with about 6 GB.
As for your specific problem, it is related to Clang's dependency on GCC-related packages for headers and libraries. See, for example, Fedora 21 with clang, without gcc.
Even if you installed GCC 4.8.2 and adjusted the path to use gcc and g++ from 4.8.2, Clang may still be looking in the old GCC directories for headers and libraries. CMake first tries to compile a C++ test file that includes the header atomic, which does not exist in the old GCC. So, it then tries to link a C test program that uses the library libatomic, which again doesn't exist in the old GCC. You can see this by looking at llvm/cmake/modules/CheckAtomic.cmake mentioned by usr1234567. CMakeError.log and CMakeOutput.log can also provide valuable insight. BTW, when I was building Swift on CentOS 7.1, I didn't run into this problem because GCC 4.8.2 was used by Clang for headers and libraries and the atomic header was found, so the C++ file got compiled. However, had the libatomic check been done, it would have failed, because libatomic.so in the repository-provided 4.8.2 has INPUT ( <name of some non-existent file> ), so trying to link with libatomic errors out.
I'm sure there are various ways of dealing with this issue, but what solved the problem for me was setting the following environment variables, please adjust to your specific setup:
export CPLUS_INCLUDE_PATH=/opt/gcc-4.8.2/include/c++/4.8.2:/opt/gcc-4.8.2/include/c++/4.8.2/x86_64-unknown-linux-gnu
export LIBRARY_PATH=/opt/gcc-4.8.2/lib64:/opt/gcc-4.8.2/lib/gcc/x86_64-unknown-linux-gnu/4.8.2
Also make sure that your 4.8.2 version of libstdc++.so is available to the dynamic linker at runtime. Since you don't have root, do
export LD_LIBRARY_PATH=/opt/gcc-4.8.2/lib64
If you had root, you could use ldconfig.
Before you start building Swift, you may want to try building, using Clang, a simple C program linking it with libatomic (the code doesn't actually have to use any symbols from the lib) and a simple C++ program that includes the <atomic> header. When compiling the C++ program, use the -std=c++11 compiler flag. If the C++ program compiles successfully, then it is not necessary for the libatomic linking test to be successful.
Interestingly, the CMakeOutput.log file still did not report finding GCC 4.8.2 as a candidate GCC installation, but the configuration/build worked well past the error.
Hopefully this helps. Please let us know if you run into something else.
CheckAtomic.cmake seems to be part of LLVM. I found a file at Github and it tries to find '__atomic_fetch_add_4' from libatomic
check_library_exists(atomic __atomic_fetch_add_4 "" HAVE_LIBATOMIC)
This fails for you. Check CMakeFiles/CMakeError.log to get more details why this test failed. Or try this line in a new project.
I have a Synology DS212j NAS (cpu Feroceon 88FR131 rev 1 (v5l)) with the optware ipkg installed. I am trying to build mongo-nonx86 on it.
"scons all" gives me the following messages:
scons: Reading SConscript files ...
scons version: 2.0.1
python version: 2 5 6 'final' 0
Checking whether the C++ compiler worksyes
Checking for C library stdc++... no
can't find stdc++ library which is needed
I have the stdc++ library installed, I also have ssl installed. My underlying question is how can I get scons to tell me more about what is really missing, where it is looking, how it is looking etc. I have so far found no options which generate any more useful diagnostic output?
Obviously a ready-made solution for getting mongodb working on this great little box would be even more welcome :-)
Well even if you do have it installed, it doesn't seem to think so, here is what I would try to do, install libssl-dev, then try to install the dev package for libstdc++, which is: libstdc++-dev.
Then see if you can compile it.
I know this issue already discussed (include there), and no one time. But, unfortunately, I cannot solve this problem.
So, I have OS X Lion, i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1, and I try to build gcc-4.7.0.
First of all, I've already built this compiler on Debian GNU/Linux, so I was sure any problems will not be...
So, I read this GCC manual and I did all exactly as described:
cd gcc-4.7.0
./contrib/download_prerequisites
cd ..
mkdir gcc_build
cd gcc_build
/Users/dshevchenko/Downloads/gcc-4.7.0/configure --prefix=/Users/dshevchenko/Tools/GCC
make
So, MPC, MPFR and GMP was successfully downloaded, and ./configure was OK. But after few minutes after make I get this error:
checking for suffix of object files... configure: error:
in `/Users/dshevchenko/Downloads/gcc_build/x86_64-apple-darwin11.4.0/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
As I understand this can't be due error of dynamic linking with MPFR, MPC or GMP, because these libs was built inside of GCC source code tree.
In my ~/.bash_profile:
export DYLD_LIBRARY_PATH=/Users/dshevchenko/Tools/GCC/lib
Help me please, I'll be grateful for any advice.
Be sure you have the latest Xcode (4.4 at the time of this writing). There is a bug in the llvm compiler in some versions of Xcode (including 4.1, which I had). For Xcode 4.4, the command line tools must be downloaded from the Xcode preferences.
the follow solution helped me out:
$ export CC="gcc -D_FORTIFY_SOURCE=0”
$ $srcdir/configure ...
$ make
source: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50342
I would like to build a clang source to source translator plugin for cuda language.Unfortunately i am not able to build the clang plugin itself.I have tried the method suggested by google to copy and paste the PrintFunctionNames and build the same and the other one suggested by http://getoffmylawnentertainment.com/blog/2011/10/01/clang-plugin-development-tutorial/ website did not work for me.
While building with google method I get:

This did not work for me How to build clang/examples/PrintFunctionNames?

I am using ubuntu 10.10 and cmake 2.8.1 to build the clang plugin.
Clang Version:3.1
please help me to build the clang plugin...
Thank you
Building programs that link with Clang can be tricky, especially if you want to do it "out of source" - i.e. in your own source tree, not as part of Clang's.
I'm maintaining a Github repo called llvm-clang-samples that provides samples of linking with LLVM and Clang, and has an example Clang plugin. This repository tries to keep up to date with top-of-tree LLVM & Clang and has branches for earlier released versions.
this error is coming because you have plainly copied the contents of CMakeLists.txt. Particularly the LLVM_LIBS and the CLANG_LIBS part.
What you have to do is simply put backslashed after every line like this
set( CLANG_LIBS \
libclang \
clangFrontend \
.. \
...
)
Or you can bring all the library names to one single line, whichever suits you.
hope this helps
First steps are always hard. Created a toy repo on github, which does pin down the build system issues for a clang plugin. Checkout the 'empty' tag.
