ninja fails to compile on PPC for bad -arch

[rmottola (Riccardo)]

On 10.5 PPC when forcing compiler gcc4.8 (default compiler is not good enough) compilation fails with:

/opt/local/bin/gcc-mp-4.8  -I. -Iinclude -Iapps/include  -fPIC -fno-common -arch ppc -std=gnu9x -Wa,-force_cpusubtype_ALL -pipe -Os -arch ppc -DB_ENDIAN -DOPENSSL_PIC -DOPENSSLDIR="\"/opt/local/libexec/openssl3/etc/openssl\"" -DENGINESDIR="\"/opt/local/libexec/openssl3/lib/engines-3\"" -DMODULESDIR="\"/opt/local/libexec/openssl3/lib/ossl-modules\"" -D_REENTRANT -DOPENSSL_BUILDING_OPENSSL -DZLIB -DNDEBUG -I/opt/local/include  -c -o apps/lib/libapps-lib-app_libctx.o apps/lib/app_libctx.c
gcc-mp-4.8: error: unrecognized command line option '-arch'
gcc-mp-4.8: error: unrecognized command line option '-arch'
make[1]: *** [apps/lib/libapps-lib-app_libctx.o] Error 1

I think a '=' is missing

[rmottola (Riccardo)]

is -arch=ppc acceptable at all?

[kencu (Ken)]

as of gcc6 (I believe) one arch argument is accepted.

gcc48 doesn't take it.

Actually this is a dependency, openssl3! sorry for the confusion... let me clean and rebuild with no compiler, then retry ninja as on intel

This bug is invalid if macports run with the compiler it selects, sorry for the noise.
