How would one approach adding support for https://github.com/tianocore/edk2-libc, say I want to include stdio and use printf in my edk2 application? I followed StdLib/Readme.txt, and am able to successfully build examples in the AppPkg, however, when I try to add StdLib to my project I get errors like these:
LibString.lib(Searching.obj) : error LNK2005: strspn already defined in LibString.lib(Searching.obj)
LibCtype.lib(CClass.obj) : error LNK2005: isspace already defined in LibCtype.lib(CClass.obj)
(...)
LibC.lib(Main.obj) : error LNK2001: unresolved external symbol main
I do have the boilerplate (!include StdLib/StdLib.inc) added to my dsc file and in inf, I have StdLib.dec added to Packages and LibC and LibStdio added to LibraryClasses. I am using VS2017 toolchain for compilation and am using edk2-stable202108 release.
I was able to achieve this using below configuration for Hello Application of AppPkg.
Hello.inf
[Defines]
INF_VERSION = 0x00010006
BASE_NAME = Hello
FILE_GUID = a912f198-7f0e-4803-b908-b757b806ec83

#include <stdio.h>
int
main (
IN int Argc,
IN char **Argv
)
{
printf("Hello, world!\n");
return 0;
}
What I have understood is that LibC has ShellAppMain() defined in it which internally calls extern main(). So You need to provide definition of main() in your source just like I did in Hello.c

I have the same problem.
Inspired by the link below, I have solved it.
https://github.com/vadimcn/vscode-lldb/issues/410#issuecomment-786791796
The reason is that I have installed NVIDIA Nsight.
As shown below, the msdia140.dll for Nsight has been loaded by codelldb.
Run PowerShell as administrator. Execute the command below to register the component. Then codelldb works.
regsvr32.exe C:\Users\【user name】\.vscode\extensions\vadimcn.vscode-lldb-1.6.8\lldb\bin\msdia140.dll
Update
For newer versions, the DLL has moved to another folder:
regsvr32.exe C:\Users\[user name]\.vscode\extensions\vadimcn.vscode-lldb-1.8.1\adapter\msdia140.dll
I'm trying to download a package with a version that is not on nixpkgs. To do so, I'm using builtins.fetchGit. Here's a summary of the file where I use fetchGit (/etc/nixos/home/core.nix) for a better idea:
{ pkgs, username, homeDirectory }:
############################
# Custom package snapshots #
############################
let custom-ver-pkgs = {
# Haskell Language Server
hls = let pkgsSnapshot = import (builtins.fetchGit {
name = "custom hls version";
url = "https://github.com/nixos/nixpkgs-channels/";
ref = "refs/heads/nixpkgs-unstable";
rev = "2c162d49cd5b979eb66ff1653aecaeaa01690fcc";
}) {}; in pkgsSnapshot.haskellPackages.haskell-language-server;
};
in
{
# Actual config
}
And here's the point where I use the hls keyword defined above:
# Packages
home.packages = with pkgs; [
... # Normal packages
] ++
# Packages with custom version (See start of file)
(with custom-ver-pkgs; [
hls
]);
As you can see, I also use home-manager. The above-mentioned .../core.nix file is imported directly into /etc/nixos/configuration.nix.
As the title says, if I run sudo nixos-rebuild switch, the terminal freezes (in the sense that the command goes on forever without doing anything). What could my problem be?
I have two c++ files named as "animal.cpp" and "zoo.cpp". These files are compiled as a shared library "zoo.so". I want to access the functions defined in these files from Python interpreter.
However, I am getting errors. I tried to do some changes but getting different kind of errors. I hope expert of Boost-Python may guide me in solving these issues.
Note: To keep the problem simple, I have not used classes, otherwise I could easily make classes of "animal" and "zoo".
I want to access both files function from Python.
Any guidance will be highly appreciated.

I have created a shared library using following command:

Considering the suggestion given by Dan for my previous issue. Now I have created a separate file pyintf.cpp containing the following code:
BOOST_PYTHON_MODULE(pyintf) {
def("hello_zoo", hello_zoo);
def("getname_zoo", getname_zoo);
def("hello_animal", hello_animal);
def("getname_animal", getname_animal);
}
but when I compile and create a shared library using the following command:
g++ -shared -o pyintf.so -fPIC pyintf.cpp -lboost_python -lpython2.7 -I/usr/include/python2.7
I get following error when I import the "pyintf" module in python.
import pyintf
Traceback (most recent call last):
File "", line 1, in
ImportError: ./pyintf.so: undefined symbol: _Z9hello_zoov
Can anyone tell what I am not doing correctly?
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The issues were resolved by putting all methods which I wanted to expose in a single pyintf.cpp. The errors which I got after update were due to missing header files and source files.
Now, the above issue has resolved by adding header files (zoo.h, animal.h) and source files (zoo.cpp, animal.cpp) in the compilation command. g++ -shared -o pyintf.so -fPIC pyintf.cpp animal.h animal.cpp zoo.h zoo.cpp -lboost_python -lpython2.7 -I/usr/include/python2.7
Thanks Dan for corrections.
The Qt page does not list pre-compiled Qt 5 packages for Solaris. Searching around, it does not seem to be included in the popular package repository OpenCSW, either. Some google hits suggest that building Qt 5 under Solaris involves some work under Solaris 10.
Thus my question: How to build Qt 5.2 under Solaris 10?
Basically it is:
cd qt-everywhere-opensource-src-5.2.0
./configure -prefix $MY_PREFIX -opensource -confirm-license -nomake tests \
-R /opt/csw/lib/64 -R /opt/csw/X11/lib/64 -qt-xcb -platform solaris-g++-64 \
-verbose
gmake -j16
gmake -j16 install
plus some adjustments because Qt 5 does not seem to be used on
Solaris much, yet.
Adjustments
Obtain the source
wget http://download.qt-project.org/official_releases/qt/5.2/5.2.0/single/qt-everywhere-opensource-src-5.2.0.tar.gz
md5sum qt-everywhere-opensource-src-5.2.0.tar.gz
228b6384dfd7272de00fd8b2c144fecd qt-everywhere-opensource-src-5.2.0.tar.gz
If the system does not habe md5sum you can use openssl md5 filename instead.
Install dependencies
I recommend to use OpenCSW because we need some dependencies to build Qt. The most important ones are:
CSWlibxcbdevel
CSWlibicu-dev # soft-dependency
CSWgcc4g++
CSWgmake
I suggest to use GCC to compile Qt. I am not aware of any advantages using the C++ compiler from Solaris Studio. On the contrary, the level of C++/STL support of this compiler may be not sufficient for a lot of use cases.
Setup environment
Make sure that you environment is clean. That means that /opt/csw/bin comes first and no LD_LIBRAYR_PATH* variables are set.
To simplify things it is probably a good idea that some directories are removed from PATH. For example such that no cc, CC commands from a Solaris Studio installation are accidentally picked up (e.g. during the compile of a bundled 3rd party component.
Adjust the specs
The software under /usr/sfw is just too outdated. /opt/csw from OpenCSW is a better replacement. Then the X-Open version is not sufficient for some used system functions.

Fix the shell
Solaris comes with a /bin/sh that violates POSIX to an extend such
that Qt's configure scripts and even shell-code in qmake-generated
code fails.
POSIX does not specify that /bin/sh has to be conforming it just specifies that the system must have a conforming shell available 'somewhere'. On Solaris it is e.g. under /usr/xpg4/bin/sh. The portable way to get a conforming shell is to search for it in the directories returned by getconf CS_PATH ...
Anyways, my choice for Solaris is to just use /usr/bin/bash:

Fix the ICU test
Solaris 10 comes with an outdated libicu - which is missing features Qt 5 needs. Thus, we simply extend the icu-test. Then either no ICU-support is build or proper one in case we install a recent libicu e.g. via OpenCSW.

Fix deep mkdir
Qt does a 'deep' mkdir() (e.g. something like mkdir -p for e.g. creating a directory hierarchy, e.g. ~/.config/company/product.

Pthreads
Solaris does not have pthread_get_stacksize_np (the _np suffix stands for non-portable).
Solaris has another function for getting stack-address/size values. My attempt:

I recommend a careful review of that code because my Qt-code does not use that Qt-module, thus, I did not test it much.
XKB extension
Qt 5 seems to heavily rely on the XKB extension. It seems that you can't build Qt 5 without XKB support. It comes bundled with xkbcommon.
First, make sure that it finds the right XKB database. Otherwise keyboard input does not work at all in your Qt programs!
Solaris does not have the default value /usr/share/X11/xkb. It has instead:
/usr/X11/lib/X11/xkb
/usr/openwin/lib/X11/xkb
But I havn't had luck with those - xkbcommon simply could not find any components with those.
I ended up with copying /usr/share/X11/xkb from a cygwin distribution to a custom path and configuring that as XKB database.
Whatever XKB you choose you have to configure it:
--- a/qtbase/src/3rdparty/xkbcommon.pri
+++ b/qtbase/src/3rdparty/xkbcommon.pri
## -1,7 +1,12 ##
QMAKE_CFLAGS += -std=gnu99 -w
INCLUDEPATH += $$PWD/xkbcommon $$PWD/xkbcommon/src $$PWD/xkbcommon/src/xkbcomp
+solaris-g++-64 {
+DEFINES += DFLT_XKB_CONFIG_ROOT='\\"/MY/XKB/CHOICE\\"'
+} else {
DEFINES += DFLT_XKB_CONFIG_ROOT='\\"/usr/share/X11/xkb\\"'
+}
### RMLVO names can be overwritten with environmental variables (See libxkbcommon documentation)
DEFINES += DEFAULT_XKB_RULES='\\"evdev\\"'
For testing it also make sense to check for NULL values in error message parameters:
--- a/qtbase/src/3rdparty/xkbcommon/src/xkbcomp/xkbcomp.c
+++ b/qtbase/src/3rdparty/xkbcommon/src/xkbcomp/xkbcomp.c
## -68,8 +68,11 ## text_v1_keymap_new_from_names(struct xkb_keymap *keymap,
log_err(keymap->ctx,
"Couldn't look up rules '%s', model '%s', layout '%s', "
"variant '%s', options '%s'\n",
- rmlvo->rules, rmlvo->model, rmlvo->layout, rmlvo->variant,
- rmlvo->options);
+ rmlvo->rules, rmlvo->model,
+ rmlvo->layout ? rmlvo->layout : "(NULL)",
+ rmlvo->variant ? rmlvo->variant : "(NULL)",
+ rmlvo->options ? rmlvo->options : "(NULL)"
+ );
return false;
}
There is also the possibility that your XServer does not even support the XKB extension. Again, I don't know if Qt 5 can be configured with disabled-XKB-support under X.
You can check your X-server like this:
xprop -root | grep xkb
Or call a random xkb-program, e.g.:
xkbvleds
Such call should not result in an error like:
Fatal Error: Server doesn't support a compatible XKB
In case your XServer does not have XKB - Qt programs are likely to segfault. Qt does not seem to really check for XKB support. It does not seem to have a fallback mechanism when XKB is not usable.
Examples
Some examples fail because of module quick not being found:

## -1,4 +1,4 ##

They are also built without.
make install
A gmake install surprisingly triggers the compilation of several modules not yet compiled. Thus it make sense to execute it in parallel:
$ gmake -j16 install
(assuming that your system has a sufficient number of cores)
QtHelp
The bundled QtHelp module is not build/installed with the main compile/install steps.
To fix that:
cd qttools
PATH=$MY_PREFIX/bin:$PATH qmake
gmake
gmake install
Open issues
when using a remote Cygwin-X connection some colors are weird - e.g. the standard widget-gray is some light-light-blue - any ideas where to start to look for that?
QtSVG is successfully built but displaying a small SVG (e.g. inside a QLabel) hangs the dialog - a truss -u : shows function calls inside libm/QtWidget - perhaps the system is just way too slow and/or some code-path is not optimized on Solaris/in combination with a X-forwarding over ssh
a Qt-Program prints on startup: Qt Warning: Could not find a location of the system's Compose files. Consider setting the QTCOMPOSE environment variable. - no idea what feature this is about
Conclusion
With those adjustments 'normal' Qt programs (without QtSvg) compile
and run fine under Solaris 10.
