Hello, all: I have been trying to build hugs on varoius RedHat platforms. While hugs98-Nov2002 works for me, anything newer fails. I am currently playing with hugs98-20041101. It seems to configure well (with ./configure ), and then tells me to do "make ; make install'. That however always breaks, ending in the following: cd .. ; env HUGSDIR='hugsdir' HUGSFLAGS=' ' src/ffihugs +G +L'hugsdir/libraries/Hugs/Storable_aux.c' Hugs.Storable make[1]: *** [../hugsdir/libraries/Hugs/Storable.so] Error 1 This seems like it should be the last step in the libraries/Makefile That is, the src is built, it also seems that the convert_libraries finishes, and then it tries to build Storable.so under hugsdir/libraries/Hugs/ and there ffihugs fails. The debugger revealed that ffihugs first tries to open Hugs.Prelude, which it finds, as hugsdir/libraries/Hugs/Prelude.hs, and then it also tries to find Prelude , which ought to be hugsdir/libraries/Prelude.hs (or something); it fails to find that file and it bails returning error code 1. In the hugs98-Nov2002, there is both a libraries/Hugs/Prelude.hs (large) and a libraries/Prelude.hs (small, includes the former). Is there a file missing? Am I doing something wrong? Please help, Victor Secarin
