I have been trying to build or1ksim on my linux machine. ./configure --target=or32-rtems --prefix=/opt/or32-rtems is sucessful. When I try to do make all install I get compilation error and make fails. The error is the following : macro names must be identifiers : warning: extra tokens at end of #define directive I appreciate any help to fix this problem. Thanks. --babu For your information I am including the error messages I got. cd ../or1ksim && automake --gnu Makefile --add-missing perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "eng" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). cd . \ && CONFIG_FILES=Makefile CONFIG_HEADERS= /bin/sh ./config.status creating Makefile cd ../or1ksim && autoheader make all-recursive make[1]: Entering directory `/home/manoj/babu/or1k/b-or1ksim' Making all in cpu make[2]: Entering directory `/home/manoj/babu/or1k/b-or1ksim/cpu' cd ../../or1ksim && automake --gnu cpu/Makefile perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "eng" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). cd .. \ && CONFIG_FILES=cpu/Makefile CONFIG_HEADERS= /bin/sh ./config.status creating cpu/Makefile make[2]: Leaving directory `/home/manoj/babu/or1k/b-or1ksim/cpu' make[2]: Entering directory `/home/manoj/babu/or1k/b-or1ksim/cpu' Making all in common make[3]: Entering directory `/home/manoj/babu/or1k/b-or1ksim/cpu/common' cd ../../../or1ksim && automake --gnu cpu/common/Makefile perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "eng" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). cd ../.. \ && CONFIG_FILES=cpu/common/Makefile CONFIG_HEADERS= /bin/sh ./config.status creating cpu/common/Makefile make[3]: Leaving directory `/home/manoj/babu/or1k/b-or1ksim/cpu/common' make[3]: Entering directory `/home/manoj/babu/or1k/b-or1ksim/cpu/common' gcc -DHAVE_CONFIG_H -I. -I../../../or1ksim/cpu/common -I../.. -I../../../or1ksim -I../../../or1ksim/cpu/common -I../../../or1ksim/cpu/or1k -I../../../or1ksim/cpu/ -I../../../or1ksim/cache -I../../../or1ksim/mmu -I../../../or1ksim/bpb -I../../../or1ksim/peripheral -I../../../or1ksim/tick -I../../../or1ksim/peripheral/channels -I../../../or1ksim/pm -I../../../or1ksim/pic -I../../../or1ksim/debug -I../../../or1ksim/vapi -I../../../or1ksim/support -I../../../or1ksim/cuc -g -O2 -D -c ./../../or1ksim/cpu/common/abstract.c : macro names must be identifiers : warning: extra tokens at end of #define directive make[3]: *** [abstract.o] Error 1 make[3]: Leaving directory `/home/manoj/babu/or1k/b-or1ksim/cpu/common' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/manoj/babu/or1k/b-or1ksim/cpu' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/manoj/babu/or1k/b-or1ksim' make: *** [all-recursive-am] Error 2
