Development / Re: Guide for building C::B on Linux request due to wiki 502 error
« Last post by AndrewCot on September 10, 2021, 06:11:57 am »
Watch out when build C::B via workspace and/or project file on Linux as some of the project files include references to GTK2 like the following:

               <Add option="`pkg-config gdk-2.0 --cflags`" />
               <Add option="`pkg-config --libs gtk+-2.0`" />

Hope this of some use for the future. Now for me to start working on getting the projects files to build with GTK3.
In addition to checking out the GNU page,  I would also suggest you have a look at the following as it goes through setting up a project and compiling a sample program.
This is not realy an Code::Blocks question.

There are C++20 features and libraries that my current CodeBlocks installation [20.03] doesn't have, causing a "no such file or directory" error on those "#include" statements in a third-party header file that my program uses, specifically "stduuid".
[bold]List of those #include statements that causes errors[/bold]
- #include <string_view>
- #include <optional>
- #include <span>
So I'm curious what version of C++ does my C::B installation have, since it also has the MinGW GCC compiler installation shipped with. The version of the compiler btw is 8.1.0.

@cacb than you very much for the script.
You're welcome, thanks for the updates on GTK3 packages. I am building under Kubuntu 20.04 and find GTK2 works best in my case, but will be ready for GTK3.

Maintaining such a script is easier than a wiki I guess.

M_PI is not part of the C standard but part of POSIX. Most probably the OP is using GCC and that one is more strict regarding the standard. Using a C standard with GNU extensions does help in that case, e.g. instead of using --std=c11 use --std=gnu11.

Small update:

I have installed GCC 11.1.0 and have successfully built C::B with iGCC 11.1.0 and it runs.
Attached is the system information collected from Xubuntu 20.04 virtualbox guest using my latest C::B source code that I just successfully compiled under Linux.

If anyone thinks that I should add extra output for Linux that will help in trouble shooting C::B issue please let me know and I will try to add it.

@cacb than you very much for the script. I used it instead of the WIKI doc as the WIKI was for WxWidget 2.8 and as such was way out of date. I used GTK3. I was able to build and run the SF 12529 trunk code.

I had to add a few more packages from the default xubuntu- install (on Virtualbox using a script) to get it to compile and remove the  --with-wx-config="$WX_CONFIG_FULLPATH" ./configure option as the wxconfig was not in the directory specified, but was in the path.

My updated script is below:

#---- install build essentials for codeblocks with gtk2 and gtk3 ----
sudo apt install -y git
sudo apt install -y cmake
sudo apt install -y build-essential
sudo apt install subversion
sudo apt install -y libhunspell-dev libgamin-dev
sudo apt-get install libboost-system-dev

#-------- install build packages for codeblocks with gtk2 --------
# GTK2 #sudo apt install -y libgtk2.0-dev 

#-------- install build packages for codeblocks with gtk3 --------
sudo apt install -y libgtk-3-devmake
sudo apt install -y libwxgtk3.0-gtk3-0v5 libwxgtk3.0-gtk3-dev

# -----------------------------------------------------------------

#path to wxWidgets configuration scripts

#actual wxWidgets configuration to use
#to see alternatives use: find /usr/local/lib/wx/config/*

#build and install paths

#create build area
mkdir -p "$CB_BUILD_PATH"
pushd    "$CB_BUILD_PATH"
#git clone codeblocks_git
#cd codeblocks_git
svn checkout codeblocks_sf
cd codeblocks_sf

# -----------------------------------------------------------------

#configure, build & install using selected configuration
./configure --with-contrib-plugins=all             \
#./configure --with-contrib-plugins=all             \
#            --with-wx-config="$WX_CONFIG_FULLPATH" \
#            --prefix="$CB_INSTALL_PATH"

make install
ls -l "$CB_INSTALL_PATH/bin"

Below is the VirtualBox script I use to install the initial XUbuntu and then did an upgrade and ran the script. I hope this may save you time in the future if you need to use VB as it can be modified for Windows very easily as most of the lines are for configuring the Virtualbox common HDD, Network, Video, Sound and serial port settings.

The file "gp_Dir2d.lxx" that I found in opencascade project was never meant to be treated as a source file as in being compiled.
Instead it should be treated as a header file and the compiling and linking turned off for the file.

So, the file extension of "lxx" should not be a problem. Still waiting for a build log!
