I'm in the process of investigating this, but I wasn't ready for it to become an issue for xemacs-beta so soon. But I'll throw some thoughts out there now. First, a question: shouldn't we have this patch?? --- configure.in.old +++ configure.in ＠＠ -1941,7 +1941,7 ＠＠ AC_MSG_CHECKING("for runtime libraries flag") case "$opsys" in sol2 ) dash_r="-R" ;; - decosf* | linux* ) dash_r="-rpath " ;; + decosf* | linux* | irix*) dash_r="-rpath " ;; *) dash_r="" for try_dash_r in "-R" "-R " "-rpath "; do Secondly, my setup is a little unusual - broken MIT X11 installed in /usr/local and libwnn installed in /usr/lib but not /usr/lib32. Man pages are not installed :-(. In other words, a typical real-life system. I haven't figured out how to make configure deal sanely with this setup yet. You are trapped in a twisty maze of directories. In every one there is a libX11, each slightly different: $ ll /usr/local/lib/libX11.* /usr/lib*/**/libX11* | grep -v '.->' -rw-r--r-- 1 root sys 1551960 Jan 2 1996 /usr/local/lib/libX11.a -rw-r--r-- 1 root sys 1826704 Oct 8 1996 /usr/lib64/libX11.so.1 -rw-r--r-- 1 root sys 1500576 Oct 8 1996 /usr/lib/abi/libX11.so.2 -rw-r--r-- 1 root sys 1592652 Oct 9 1996 /usr/lib32/libX11.so.1 -rw-r--r-- 1 root sys 1471032 Oct 9 1996 /usr/lib/libX11.so.1 I (re)discovered that --x-includes=/usr/include is a BAD idea when using gcc. /net/wanchai/export1/xemacs/local/irix/bin/gcc -c -fno-exceptions -O3 -Wall -Wpointer-arith -Winline -Wmissing-prototypes -Wmissing-declarations -Wunused -Wformat -Wno-switch -Wno-sign-compare -Wno-uninitialized -Wshadow -Demacs -I. -DHAVE_CONFIG_H -I/net/wanchai/export1/xemacs/local/irix/include -I/usr/include /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c: In function `maybe_call_magic_handler': /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: warning: implicit declaration of function `__NO_CFOLD_WARNING' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: warning: implicit declaration of function `__builtin_alignof' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `Lisp_Object' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `Lisp_Object' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `Lisp_Object' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `Lisp_Object' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: warning: implicit declaration of function `__builtin_classof' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `Lisp_Object' /tmp_mnt/net/wanchai/export1/xemacs/home/martin/x/ws/21.0/src/symbols.c:2879: parse error before `)' Martin
