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' (Now fixed in Haiku)

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

The stat struct in sys/stat.h in BeOS and Haiku ( Haiku now has it  as seen here) doesn't have an st_blocks member. In projects with autoconf, you can check for HAVE_STAT_ST_BLOCKS.

-lm

ports: dev-lang/lua, others

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

Please DO NOT create a shortcut of libroot.so and rename to libm.so on gcc4 and gcc2 lib directory (Haiku hybrids case) or change the -lm references in the configure file to -lroot. If the port is using the autotools chances are this can be fixed by doing an AC_CHECK_LIB for cos in m and then setting a variable such as LIBM or MLIB to by ="-lm" if true or "" if not.

Here is some explanation:  http://www.freelists.org/archives/haiku-development/04-2008/msg00904.html

-lc

This sometimes turns up, and I think it is due to the port using an older libtool. Try running libtoolize --force --copy --install, aclocal, autoconf and automake before ./configure to see if that clears it up.

conflicting types for `restrict' (Now fixed in Haiku)

/boot/develop/headers/posix/search.h:35: conflicting types for `restrict' /boot/develop/headers/posix/search.h:35: previous declaration of `restrict' This seems to be an issue with Haiku and has been reported  Haiku-2262 This has been fixed in Haiku. If using a version prior to the fix you can copy the search.h file over the one in your headers/posix folder.

GCC 2.9 related build problems

output_operand_lossage `invalid expression as operand'

This can be avoided by not passing the '-g' option to gcc for this test.

GCC 4.3 related build problems

Typical errors look like these:

error: 'find' is not a member of 'std'

error: 'exit' was not declared in this scope

Please take a look at:  http://www.cyrius.com/journal/2007/05/10#gcc-4.3-include

MSG_NOSIGNAL undeclared

Add below to header/source file.

#ifndef MSG_NOSIGNAL 
#define MSG_NOSIGNAL 0 
#endif

stdbool.in.h (Now fixed in Haiku)

This has been fixed: http://ports.haiku-files.org/wiki/dev-libs/gnulib So any releases posted AFTER May 25, 2008 'should' include an updated stdbool.in.h

iconv (Now fixed in Haiku))

Iconv is included in Haiku, but many times ./configure does not detect and use it. This is because it is in libtextencoding.so ( should be fixed now). So try adding a check for iconv in libtextextencoding and see if that works.
