canonical libtiff problems

[paulotex]

I've been struggling to compile libtiff with no success for the last 24h. Perhaps someone can help me with it. I think it involves some autoconf magic. Here it goes:

* First I got the source from libtiff.org: 3.8.2

* Then I did the usuall config/config.sub patch to add the psp allegrex. Ran autoconf.

*

Code: Select all

LDFLAGS="-L`psp-config -p`/lib -lc -lpspuser" ./configure --host=psp --prefix=`psp-config -P` --disable-shared

This _seems_ to work fine.

* make failes with:

Code: Select all

libtool: link: CURRENT `' must be a nonnegative integer
libtool: link: `3:8:2' is not valid version information

* So I patched config/ltmain.sh:

Code: Select all

+++ ../tiff-3.8.2-psp2/config/ltmain.sh	2008-09-21 07:41:34.000000000 +0100

Ran configure again (to recreate libtool) and make.

* This times it fails with:

Code: Select all

/Volumes/Extra/Users/paulo/pspdev/bin/../lib/gcc/psp/4.3.1/../../../../psp/lib/libc.a(lib_a-getopt.o):(.bss+0x4): multiple definition of `optind'
../port/.libs/libport.a(getopt.o):/Users/paulo/Documents/PSP/Apps/Bookr/Arrr/tiff-3.8.2-psp/port/getopt.c:56: first defined here

After lots of research, I found out that it is getting duplicate symbols because during "configure" it could _not_ detect "getopt", so it compiled its own version. But because getopt exists, they are now conflicting.

* The reason configure failed detecting getopt is here, in config.log:

Code: Select all

 psp-gcc -o conftest -g -O2 -Wall -W -I/Users/paulo/include  -L/Users/paulo/pspdev/psp/sdk/lib -lc -lpspuser conftest.c -lm -lc  >&5
/Volumes/Extra/Users/paulo/pspdev/bin/../lib/gcc/psp/4.3.1/../../../../psp/lib/libc.a(_write.o): In function `_write':
libcglue.c:(.text+0x84): undefined reference to `sceIoWrite'

If I remove the last -lc and put -lm _before_ conftest.c, the getopt test compiles fine.

So this is where I'm stuck. How can I tell autoconf to place the libs _before_ the source file? Why is it adding -lc when it is already there? Even if I solve this issue, -lc at the end will bite me again later for sure.

I'm sure this problem has occurred before with other libs based on autotools. How did other developers solve it?

Thanks

Sorry to answer my own post, but I solved the problem. In configure.ac, after checking for the fundamental libs (in libtiff, it's just libc and libm), just add:

Code: Select all

dnl For PSPSDK, Make sure we add "-lc -lpspuser" at the end
case "$target" in
     *-psp-*)
	LIBS="$LIBS -lc -lpspuser"
     	;;
     *)
	;;
esac

"make" still breaks in the "tools" folder, but that is fine by me, "make install" installs the libs and the headers just fine.

[paulotex]

Here's the summary, in case any one is interested. This can also be helpfull for other autotools projects:

* Edit config.sub and add the mipsallegrex-psp target.
* Edit ltmain.sh and fix version_type. This fix might break the configure on other systems.
* Edit configure.ac and make sure LIBS has "-lc -lpspuser" at the end.
* Run autoconfig.
* Configure should be run as:

Code: Select all

LDFLAGS="-L`psp-config -p`/lib -lc -lpspuser" ./configure --host=psp --prefix=`psp-config -P` --disable-shared

The errors during make and install are on the tools. The lib is fine.

[Insert_witty_name]

Adding -G0 to the CFLAGS should remove the __ctype_ptr warnings.

duh! Thanks! This is everywhere to be found, I was so obsessed with other errors that I overlooked this. With this flag the compilation of the tools advance quite well until:

iptcutil.c:8:20: error: memory.h: No such file or directory
make[2]: *** [iptcutil.o] Error 1

But as I told before, having the lib is all I needed.

Thanks for the info!
