Hi,
stdint.h is part of the C99 standard, and is not available on older systems, like Solaris and FreeBSD Stable. Use the following patch and it should work.
Thanks, that allowed the process to go on quite a bit longer (over 2 hours on Sun Ultra 5, with lots of warnings about Haskell problems in various files). Unfortunately, it then stopped abruptly with /q/pd/nhc/nhc98-1.12/targets/sparc-solaris2/obj/hattools/hatlib.a -d/q/pd/nhc/nhc98-1.12/targets/sparc-solaris2/obj/hattools -lsocket -lnsl Fail: Can't find module FFI in . Or in standard libraries at Asked for by: HatTrace.gc [Check settings of -I or -P flags?] Stop - hmake dependency error. gmake[1]: *** [/q/pd/nhc/nhc98-1.12/lib/sparc-solaris2/hat-observe] Error 1 gmake[1]: Leaving directory `/q/pd/nhc/nhc98-1.12/src/hat/tools' gmake: *** [lib/sparc-solaris2/hat-stack] Error 2 What is it that I am missing?
