No stdlib, custom startup code - GDB doesn't work

<< < (4/4)

Mr.Madguy:
If somebody is interested, for now problem with anti-virus is fixed via comparing my C++ code with similar ASM program, that doesn't have such problems. Looks like anti-viruses hate GetModuleHandle("KERNEL32.DLL"). It's better to use LoadLibrary/FreeLibrary instead.

Another question - why it's necessary to install 32bit gcc in order to compile for 32bit target (i.e. -m32)? Why there is no cross-compile option? According to error messages 64bit compiler can't find 32bit libraries when using -m32. So may be there is some way to configure paths instead of using 32bit compiler?

For "-m32" to work for complex programs; the Compiler Builder needs to build the support libraries for 32 bit. Most of the 64 bit Compilers that support "-m32" do not build very many 32 bit libraries.

It is long story.  Actually they exists, but likely you dont want them: "https://sourceforge.net/projects/mingw-w64/files/Multilib Toolchains(Targetting Win32 and Win64)/ "
My experience with multiply mingw compilers (I have now 3 actually in use, 32b, 32b for XP and 64b) is like this: I use bat files which switch path and I have different  configs in CB. And there are no big problems to switch.
