32bit application programming on 64bit Linuxes is soooo much fun!

The "dev" versions of the shared objects are not always there… which makes for a fun exercise in finding a shared object and creating a symlink for it !

I suppose I shouldn't complain too much though… in the end it all does appear to work as expected - once you've sorted out the configuration.

But it's not a painless exercise, and I expect this puts a few people off using BlitzMax on 64bit Linuxes (amongst other things that are much discussed elsewhere).

Awaiting "success reports" on this front from you brucey.

Meanwhile: enjoy the hours of pain - welcome to the club.

Well, it's all going swimmingly, as they say. Everything appears to be working. Modules build, apps run..

Wonderful :-)

Glad someone's having luck with it! I get this problem every time I try to build anything and I can't for the life of me figure it out!

Linking:twl
/usr/bin/ld: /home/david/BlitzMax/mod/pub.mod/openal.mod/openal.release.linux.x86.a(openal.c.release.linux.x86.o): undefined reference to symbol 'dlopen@@...'
/usr/bin/ld: note: 'dlopen@@...' is defined in DSO /lib/i386-linux-gnu/libdl.so.2 so try adding it to the linker command line

I know this is an old post but I was having the same issue as Devlin. Just so there is a record here, I found that writing the following in your .bmx file fixes that error

Import "-ldl"
