[SOLVED] Using CPPFLAGS to 32bit building AND point to source files simultaneously!

coltson · 09-12-2021, 06:22 PM

Hi. If I try to build a 32bit, I pass

Code:

CPPFLAGS=-m32 LDFLAGS=-m32 CFLAGS=-m32 ./configure --host=i386-linux-gnu

to configure.

However, I install all header files and their associated libraries into their own directories.

So when a program I am currently building needs to look for certain source files, I do:

Code:

CPPFLAGS=-/media/34GB/Arquivos-de-Programas/whatever/include ./configure

However, for 32bit builds, CPPFLAGS is already busy receiving "-m32"

So, what can I do to make CPPFLAGS to do both things?

CPPFLAGS="-m32 -/media/34GB/Arquivos-de-Programas/whatever/include anything_else"

Really? I just did

Code:

CPPFLAGS="-m32 -/media/34GB/Arquivos-de-Programas-Linux-32bit/xorg/X11-1.4.4/include/"  CFLAGS=-m32 LDFLAGS=-m32 ./configure --host=i386-linux-gnu

and received a:

Code:

checking for C compiler default output file name... 
configure: error: in `/home/leopoldo/Arquivos-de-Programas-Linux/Mesa-7.5.2':
configure: error: C compiler cannot create executables
See `config.log' for more details.

Reading config.log there is a:

Code:

gcc: error: unrecognized command line option '-/media/34GB/Arquivos-de-Programas-Linux-32bit/xorg/X11-1.4.4/include/'

yes, that is an invalid option. for include files you need to use

Code:

-I<dir>
