Hello,

It seems that there is a bug in makefile generation algorithm. It doesn't detect operating system (assumes POSIX=LINUX) and ignore our internal settings.

This issue can be only fixed by Mirek. Right know you could manipulate makefile and replace "-ldl -lrt" with "-execinfo". Here is our library matrix for operating systems for Core package:
index.php?t=getfile&id=6154&private=0

After building TheIDE it should run smoothly on OpenBSD. However, please build by replacing libraries and let us know what is the status. Thanks!

Sincerely,
Klugier

IMO, it is not a bug, "it is a feature". Simply put, it generates makefile for the given set of flags. As it is generated in linux, it creates Linux makefile...

This will be problematic (but not impossible) to fix.

I think the simple solution here is to generate separate makefiles for each host. Like Makefile.linux etc... Then have master makefile that invokes it based on system flags.

A bit more sophisticated solution would use some form of diff to "fix" one common makefile...

OK, I believe we should do this:

- fix U++ itself to correctly work (I mean, when you are using theide / umk to compile).

- in addition to Makefile, provide Makefile.in and configure. Makefile will be configured for Linux. Makefile.in will be a copy. configure will detect platform and patch Makefile.in for it. I believe it will be possible pro create "universal" patch that just replaces a couple of strings in Makefile - replace LINUX with correct target, change library files.

- add this to ./install as well...
