Title: tdm-gcc 32/64 bit targets under windows
Post by: Russell on July 12, 2014, 02:27:07 am
Hello :)

I need to add a 32bit target to a project I am working on. Currently I use the tdm-gcc compiler and have to add the line "-F pe-i386" in toolchain->resource compiler, this is very undesirable as it affects ALL projects that are loaded with the IDE.

Is there a better way to accomplish this? I tried overriding the $recomp variable in the target itself to: "windres.exe -F pe-i386", this does not work

Thanks

I would try file properties and see if a custom compile command/string works for a single file.
If multiple files, I am not sure what I would do.

Edit: I would guess this string
Code
$rescomp -F pe-i386 $res_includes -J rc -O coff -i $file -o $resource_output

This works perfectly, thank you stahta01 :)

For those that are curious, I placed a variable named RCFLAGS into Build Options->Custom Variables, the value is "-F pe-i386" without quotes.

Right click on the resource file in the project and go to Properties->Advanced tab, click "Use custom build command for this file" and enter:

$rescomp $rcflags $res_includes -J rc -O coff -i $file -o $resource_output

For the 64bit target, I made the RCFLAGS value empty

What is the real problem here? You're using 64bit compiler to build 32bit executables?

Why not creating a 64-bit and a 32-bit toolchain with the same compiler executables ?

I think he is building both 32 bit and 64 bit targets in the same project.

That was what I based my suggestion on.

You can have different compilers for different targets.

Yeah, but, having different CB Compilers for the same real world compiler seems wrong to me.

But, I would do it with two compilers myself; because I do NOT wish to have issues where MinGW64 headers are required to build a project by accident.

Hi All

I am using the standard tdm-gcc toolchain, which according to the manual: "TDM-GCC is a multilib bootstrap of GCC's x86_64-w64-mingw32 target, built to run on 32-bit or 64-bit Windows and generate binaries for 32-bit or 64-bit Windows.", I believe this is the same toolchain used to build the codeblocks nightlies.

I am using tdm-gcc to generate both 32 and 64 bit binaries of the same project, it works extremely well for this and I haven't encountered any mingw64 header issues at all

I could not find a solution to having both a 32 and 64 bit target in the same project, mainly due to the resource compiler. Tim's suggestion was perfect because I only have 1 resource file per project anyway

Hope that clears up the confusion
