I just found out that I can circumvent the problem by adding a line import Char to my loaded file. regards, -john

[Hugs-bugs] Suggested change
by Alwyn 26 Oct '04

26 Oct '04

This is the third time I've broached this subject over a period of time: I get a linking error when making shared libraries for Hugs; the linker complains of the absence of the '_environ' symbol. I suggest the maintainer should make the following change: $ diff configure.ac.old configure.ac 709c709 < HUGS_TRY_DYNLINK(-bundle) --- > HUGS_TRY_DYNLINK(-flat_namespace -bundle -undefined suppress) 712c712 < HUGS_TRY_DYNLINK([-bundle -lc]) --- > HUGS_TRY_DYNLINK(-bundle) Alwyn

[Hugs-bugs] building hugs98-20041008.tar.gz requires GNU find
by fool＠sdf-eu.org 21 Oct '04

21 Oct '04

I don't know if this is a bug. It just doesn't compile out-of-the-box on BSD systems. The script hugs98-20041008/src/unix/convert_libraries uses GNU find's -iname and -maxdepth.

[Hugs-bugs] Compiling Hugs on Cygwin

Hi there, I just got a new computer in my office with Windows XP on it. I freshly installed Cygwin, and then downloaded the Hugs UNIX sources. "configure" works fine, but when I try to "make", this is what happens: <<< [off/src] -: make install gcc -c -g -O2 hugs.c gcc -c -g -O2 edit.c gcc -c -g -O2 observe.c gcc -c -g -O2 builtin.c builtin.c: In function `mkThunk': builtin.c:1981: warning: use of cast expressions as lvalues is deprecated builtin.c:1985: warning: use of cast expressions as lvalues is deprecated builtin.c:1989: warning: use of cast expressions as lvalues is deprecated gcc -c -g compiler.c gcc -c -g -O2 errors.c gcc -c -g -O2 evaluator.c gcc -c -g -O2 ffi.c gcc -c -g -O2 goal.c gcc -c -g -O2 input.c gcc -c -g -O2 machdep.c machdep.c: In function `scanSubDirs': machdep.c:562: error: storage size of `findInfo' isn't known machdep.c:577: error: `_A_SUBDIR' undeclared (first use in this function) machdep.c:577: error: (Each undeclared identifier is reported only once machdep.c:577: error: for each function it appears in.) make: *** [machdep.o] Error 1 >>> I attach the full output of the making process.

I get an error while building the latest Hugs snapshot on Mac OS X 10.3.5 with Apple's version of GCC 3.3 as follows: Compiling hugsdir/libraries/System/Posix/Env.hs ld: Undefined symbols: _environ runhugs: Error occurred ERROR "hugsdir/libraries/System/Posix/Env.hs" - Error while running compilation command 'gcc -DNDEBUG=1 -g -no-cpp-precomp -flat_namespace -bundle -D__HUGS__ "-Ihugsdir/include" "hugsdir/libraries/System/Posix/Env.c" -o "hugsdir/libraries/System/Posix/Env.so" -Ihugsdir/libraries/System/Posix -Ifptools/libraries/unix/include -ldl' It's no big deal, but it would be nice if it could be resolved.
