Common Porting Problems

This page serves to collect information about common problems encountered when porting applications/libraries to the Haiku/BeOS platform. The problems should be identified by the (compiler) errors that typify them.

Information about BeOS's POSIX compatibility, see BeOSPosix.

no undefined references allowed in i586-pc-beos shared libraries

ports: dev-util/subversion, dev-libs/apr

You need to pass the -no-undefined option to libtool

Alternatively, libtool can be patched to always exhibit this behavior, at the risk of breaking static compilation when dynamic linking fails. -- andreasf

(stat) structure has no member named `st_blocks'

ports: app-arch/tar (make check), net-fs/samba?, dev-util/cvs

The stat struct in sys/stat.h in BeOS and Haiku doesn't have an st_blocks member. In projects with autoconf, you can check for HAVE_STAT_ST_BLOCKS.

missing -lm

ports: dev-util/lua?, others

You can remove the -lm. The -lm refers to libm which isn't needed for Haiku or BeOS as the math library is part of libroot and linked by default
