Hello, I can't seem to get my code to compile. I have just recently gone back to programming blizmax on windows 7 64 bit. I have installed blitzmax 1.50, mingw 3.4.5, and have copied the mingw ar and ld to blitzmax lib folder. I have also edited my environment paths. My modules compile just fine but I still get these errors while trying to build my code:

C:/programming/blitz/BlitzMax/bin/ld.exe: skipping incompatible C:/programming/blitz/BlitzMax/lib/crtbegin.o when searching for C:/programming/blitz/BlitzMax/lib/crtbegin.o
C:/programming/blitz/BlitzMax/bin/ld.exe: cannot find C:/programming/blitz/BlitzMax/lib/crtbegin.o
C:/programming/blitz/BlitzMax/bin/ld.exe: skipping incompatible C:/programming/blitz/BlitzMax/lib/crt2.o when searching for C:/programming/blitz/BlitzMax/lib/crt2.o

Whats wrong? I have also tried several mingw versions, am I using the wrong version?

Thanks

Depending on your MinGW version, you'll also need to replace a number of the MinGW libs into the Blitzmax/lib folder -- Any file that exists in blitzmax/lib as well as your mingw/lib folder, copy the mingw/lib version and overwrite the blitzmax/lib one with it.

There are some threads on this forum that contrain a command line script that can automatically do this for you.

Hi!

You may look up Brucey's topic about this here: http://www.blitzbasic.com/Community/posts.php?topic=95220

Most users compile with MinGW 4.7.x or 4.8.x these days.
Sadly, BMX doesn't support 64 Bit yet.

Thanks xlsior and Grisu. I followed Brucey's post and got it working. I still got an error though:

C:/programming/blitz/BlitzMax/lib/libmingwex.a(pformat.o):pformat.c:(.text+0x44b): undefined reference to `__umoddi3'

Which then it failed to link. To fix this all I had to do was add another environment variable:
BMK_LD_OPTS = -lmsvcrt -lgcc

Thanks everyone!

You are welcome.

If you want, Brucey also made some changes to the native bmx modules that didn't make it into the 1.50 release. Among other stuff they fix a Pixmap related memory leak. You can get the code over his repository.

Last but not least, you can also update the fasm assembler file with this one: http://flatassembler.net/fasmw17139.zip
