okay - fairly simple (I hope):
AIX 5.2 + gcc 4.2.2 = guile 1.8.3 w/not compile
Ubuntu 7.10 + gcc 4.1.2 = guile 1.8.3 compiles
BUT - when you try to compile the code snips out of hooks.h that the
error refers to - both the Linux and AIX gcc's spew identical errors.
I'm working through the gcc compile line that explodes - and I've found
one thing rather interesting --- the last compile line in
guile-1.8.3/libguile that explodes is:
gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I.. -I/opt/phs/include -D_THREAD_SAFE
-O2 -mcpu=power2 -pthread -Wall -Wmissing-prototypes -Werror
-MT libguile_la-discouraged.lo -MD -MP -MF deps/libguile_la-discouraged.Tpo
-c discouraged.c -DPIC -o .libs/libguile_la-discouraged.o
Which gives this:
In file included from ../libguile/gc.h:27,
from ../libguile.h:73,
from discouraged.c:22:
./libguile/hooks.h:43: error: expected ';', ',' or ')' before '.' token
./libguile/hooks.h:48: error: expected specifier-qualifier-list before

./libguile/hooks.h:62: error: expected declaration specifiers or '...' before

./libguile/hooks.h:66: error: expected declaration specifiers or '...' before
'scm_t_c_hook_function'
./libguile/hooks.h:67: error: expected ';', ',' or ')' before '.' token
gmake[3]: *** [libguile_la-discouraged.lo] Error 1
Now if I cd into libguile and hand-execute that line - without the -I..
elements it compiles without errors. Which argues that something else
I'm not seeing is being included that is causing the problem.
Code-monkey friend of mine suggested that the problem is with the cpp
output, but when I do this:
cpp discouraged.c -o foo.c && gcc -c foo.c
I get foo.o and no errors. Now bear in mind that I'm a C/C++ newb and
that last bit probably means nada.
You sir have hit a nail on the head - at least the compile got past
discouraged.c anyway ...

6083 return scm_c_make_polar (exp (SCM_COMPLEX_REAL (z)),
6084 SCM_COMPLEX_IMAG (z));
6085 #endif
6086 }
And I'm stuck again :p
running a 'find' now to see if func_data is showing up somewhere else being
sneaky.
