in attempt to build guile 1.8.5 i ran into this problem when compiling
libguile/filesys.c into filesys.o
.
.
.
. /usr/include/dirent.h
.. /usr/include/sys/dirent.h
filesys.c: In function `scm_readdir':
filesys.c:919: error: too many arguments to function `readdir_r'
. ../libguile/filesys.x
gmake[3]: *** [filesys.lo] Error 1
gmake[3]: Leaving directory `/usr/local/src/guile-1.8.5/libguile'
the sol10 manpage for readdir_r includes:
SYNOPSIS
#include <sys/types.h>
#include <dirent.h>
struct dirent *readdir(DIR *dirp);
struct dirent *readdir_r(DIR *dirp, struct dirent *entry);
Standard conforming
cc [ flag... ] file... -D_POSIX_PTHREAD_SEMANTICS [ library... ]
int readdir_r(DIR *restrict dirp, struct dirent *restrict
entry, struct dirent **restrict result);
with the addition of -D_POSIX_PTHREAD_SEMANTICS on the compile line
the compile succeeds. more specifically:
gcc -D_POSIX_PTHREAD_SEMANTICS \
-DHAVE_CONFIG_H -I.. -I.. -I.. -I/usr/local/include -O -H -mcpu=v9 \
-mfpu -Wall -Wmissing-prototypes -MT filesys.lo -MD -MP -MF .deps/filesys.Tpo \
-c filesys.c -fPIC -DPIC -o .libs/filesys.o
works
gcc -DHAVE_CONFIG_H -I.. -I.. -I.. -I/usr/local/include -O -H -mcpu=v9 \
-mfpu -Wall -Wmissing-prototypes -MT filesys.lo -MD -MP -MF .deps/filesys.Tpo \
-c filesys.c -fPIC -DPIC -o .libs/filesys.o
fails
i expect i will need to add something about threads to the various linker
lines in order to appropriately load the correct thread libs, but how and
where?
do i need to specify something else to configure to trigger the use of
the solaris standards conforming directive(s)?
or am i just at the mercy my older gcc and solaris10?
ahha -- maybe at the very end of the readdir_r manpage is the clue i need:
For POSIX.1c-conforming applications, the
_POSIX_PTHREAD_SEMANTICS and _REENTRANT flags are automati-
cally turned on by defining the _POSIX_C_SOURCE flag with a
value >= 199506L.

i can do.
