Codelite - all vers v6.x cause compile problem with SDL2 x86

[metamorphosis]

The error is "undefined reference to SDL_main", however if codelite v6.x is removed and v5.4 is installed (also with mingw4.8.1 TDM package) the error is resolved.
The error occurs regardless of whether SDL v2.02 or v2.03 is used.

Showing the build output will show the problem.
Seem my signature for how to post

Its not a codelite problem, as codelite is not a linker nor a compiler. You probably missing something in the settings, but I can't tell what unless I see the build log

Check the SDL dev mail list around August 24, 2014, the post "Migration paragraph about SDL_main is confusing - rewording suggestion". Whether that functions exists or is linkable depends on your platform and build settings (which you don't mention).

Not actually relevant.

It's a codelite problem-
the same project with nothing changed works perfectly in codelite v5.4 with the same mingw 3.81 tdm setup. I can uninstall/reinstall 5.4 or 6.x ad-infinitum and it makes no difference - works on 5.4, doesn't on 6.x.
There may be something related to the way codelite processes builds in 6.x that is different from 5.4, which could be what's causing the error. Either that or there's a subtle difference between the mingw 3.81 tdm installed with 5.4 to the one installed by 6.x.

Odd thought, try changing the optimization level from -O0 to -O2

[eranif]

I can't see how this is a codelite problem.
Even though you say nothing has changed, you just replaced 6.0 with 5.4, something did change...
Can you provide a minimal sample that reproduces the problem?

We're discussing a program, Belief is for religious discussions.

I didn't say nothing had changed, I said that codelite changed from 5.4 to 6.x and nothing else was changed.
Hence the problem is with codelite and nothing else.

Can you provide a minimal sample that reproduces the problem?

No, I cannot. The project is large.

Yes, I've investigated the error message as well. Those scenarios do not apply to my code.

[Gibbon1]

Can you post build output for 5.4 that works?

[metamorphosis]

Found the solution/codelite bug.
The issue is the "Exclude from Build" flag.
What I found was that in 6/7 the first file in the project (main.cpp) had this ticked for no reason,
however opening the same workspace in codelite 5.4 it was not ticked.

This was what caused the error message. Eranif, if you want the workspace file to compare between 5.4 for yourself, PM me and I'll send it to you.
