Hello, I'm using adacore gpl gnat 4.5.4 to build gcc gnat 4.7.2. I'm just trying to build it for the host system. ./configure --prefix=<somewhere>/gnat --enable-languages=ada,c ./make once it gets to make[3]: Entering directory `./gcc' it will attempt to run gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common -DHAVE_CONFIG_H -static-libgcc -o gnat1 [........] which errors out with ada/a-except.o: In function `ada__exceptions__exception_message': ./gcc/../../gcc-4.7.2/gcc/ada/a-except.adb:609: undefined reference to `__gnat_rcheck_CE_Explicit_Raise' it repeats that error for multiple functions. anyone have any tips or suggestions?? Thanks!
