[Solved] Code::Blocks and makefile: unexpected behaviour

simac · June 03, 2017, 12:40:38 PM

Hello everybody !
I'm trying to compile a wxWidgets Windows app with MinGW. To do this I'm using the makefile.gcc provided with the minimal sample.
When I compile the minimal example with

Code Select

mingw32-make -f makefile.gcc BUILD=release SHARED=1 UNICODE=1 all work perfectly. However if I use Code::Blocks and configure the project to use the makefile (Build project/target:

Code Select

$make -f $makefile BUILD=release SHARED=1 UNICODE=1 ) the compilation work properly, but the program crashes when starting.
Moreover the objects files and the executables are different between the two ways. I can't find out a reason why.
Could you help me?

Thank you in advance,
Simac

Please look at the CB build log and see what differs.

That's a part of the problem: nothing differs. The build log is exactly the same with CB and the makefile:

With the makefile:

It is very strange !

Since you posted an HTML file; I really did NOT look for differences.

But, if there is no difference the first thing to check is that you are using the exact same GCC Compiler/toolchain.

I checked the version of the compiler and it's the same with CB and the command line. I tried with a nighty-build version of CB and I've still got the problem.

Is it the exact same Compiler?

Edit: The command below in the cmd.exe prompt used to build wxWidgets should show the path of the gcc used; compare with the CB Toolchain setting.

Code Select


where gcc

or

Code Select


where gcc.exe

I didn't know this command! Very useful!

You're right, the gcc used in the cmd wasn't the same as the one used by CB... I didn't even know that I had another gcc on my computer...
I removed the unexpected location from the PATH, and all seems to work perfectly.

I would like so much banging my head against the wall, but I'm afraid I would damage the wall!

Thank you very much!
