Incompatible libraries (portlibs)?

Post by nebiun » Sun Oct 07, 2018 10:26 am

Compiling an old project with last PPC version I have this errors during linking phase:

C:/devkitPro/portlibs/ppc/lib\libfreetype.a(ftbzip2.o): In function `ft_bzip2_stream_close':
ftbzip2.c:(.text+0x3c): undefined reference to `BZ2_bzDecompressEnd'
C:/devkitPro/portlibs/ppc/lib\libfreetype.a(ftbzip2.o): In function `ft_bzip2_file_fill_output':

make: *** [Makefile:102: build] Error 2

This is the output of pacman -Sl :
# pacman -Sl | grep ppc
dkp-libs ppc-bzip2 1.0.6-1 [installato]
dkp-libs ppc-freetype 2.9-3 [installato]
dkp-libs ppc-libjpeg-turbo 1.5.3-1 [installato]
dkp-libs ppc-libogg 1.3.3-2 [installato]
dkp-libs ppc-libpng 1.6.34-1 [installato]
dkp-libs ppc-libvorbisidec 1.2.1-1 [installato]
dkp-libs ppc-mpg123 1.25.10-1 [installato]
dkp-libs ppc-mxml 2.11-1 [installato]
dkp-libs ppc-pkg-config 0.28-3
dkp-libs ppc-zlib 1.2.11-1 [installato]

It's my fault (aka: I missing to do somethings), or libfreetype was built with a wrong version of libbzip2?

Thanks for your help.

Sounds like link order to me. Make sure your LIBS line has -lfreetype -lbz2 and not the other way round.

More subtle problem: previous version of freetype library required zip library (option -lz), new version requires bz2 library (option -lbz2).
Now I need to link with both libraries because libpng requires -lz and freetype requires -lbz2.

Solved!
Thanks
