Bugzilla Bug 107428

While trying to emerge urt-3.1b I ran into the following problem

gcc   -O2 -pipe -I. -I../include     -c -o vaxshort.o vaxshort.c
rm -f librle.a
ar rc librle.a
ar: no archive members specified
usage:  ar -d [-TLsv] archive file ...

Looks like the wrong type of linker calls is used. Is it possible to do e.g a 

gcc   -O2 -pipe -I. -I../include   avg4.c -L../lib -lrle  -lm -o avg4.new

instead of a 

gcc   -O2 -pipe -I. -I../include   avg4.c ../lib/librle.a    -lm -o avg4.new

AFter a closer look, the problem seems twofold:

1) librle.a is not created (ar rc librle.a fails, because ar seem to expect a non-empty .o files list)
2) further down, rleClock.c cannot be compiled because a data type symbol is already defined elsewhere

for 1) I  attach a patch against lib/makefile which removes the faulty call
for 2) I attach a patch which renames the problematic type definition and all references from stack_t to 
stack2_t

The makes the package at least compile.

properly create the needed library

Created an attachment (id=69707) [details]
rename the ambigous data type

where is stack_t defined ?  in otherwords, post the actual error message please

also, change the ar line to just this and see if it works:
ar rc $(LIBNAME) $(OBJS)

> also, change the ar line to just this and see if it works:

I uncommented the ar rc line, the ar -q line was lef uncommented.
It built fine.

> should be fixed in cvs now
Could it please be keyworded ~ppc-macos?

it emerges fine with USE="gif tiff gs". There is some problem with USE="X".
Basically it tries to link with -lX11, but cannot find the proper library, possibly because of some missing 
-L flags.
The message is

 gcc   -O2 -pipe -I. -I../../include     -c -o XGetHClrs.o XGetHClrs.c
gcc   -O2 -pipe -I. -I../../include   getx11.o x11_stuff.o timer.o map_scan.o in_cmap.o XCopyImg.o 
XGetHClrs.o ../../lib/librle.a -lX11 -lXext -lm   -o getx11.new

collect2: ld returned 1 exit status
make[2]: *** [getx11.out] Error 1
make[1]: *** [subdirs] Error 2
make: *** [default] Error 2

If you add a -L/usr/X11R6/lib in get/getx11/makefile (variable X11LIBS), it at least compile fine.
No idea if this can be added more globally in some configure scripts....

 

I'm already looking into this... and it's weird.  I don't have a X11.h file,
only X10.h and X.h

then it sounds like OS X is built off an older version of X, namely X10

ebuild patch

Nah, I was too quick.  Linux has exactly the same files, and no X11.h too.

The stuff resides in a different dir for OSX.  I got it compiling now.

Can you agree on the attached patch?

Looks good and emerges fine

... then we wait for a comment by Der Spankmeister.

Have you tried an ebuild that links again the library yet, Dirk?

I tried to build netpbm, but there seem to be other problems to be solved, yet (#74101).

Created an attachment (id=69887) [details]
urt-X11R6-dir.patch

try this instead

patch works fine.

fixed in cvs then

not fixed in cvs, because the ebuild is not yet keyworded ppc-macos

then KEYWORD it :P

Cannot because I haven't been able to test the library by having another app
compiling/linking against it, hence I cannot guarantee it works.  QA and stuff.

checked with giflib

as ~ppc-macos in portage
