[ptxdist] build failure in xterm

[ptxdist] build failure in xterm

[Richard Cochran]

Dear list,

Using the latest git ptxdist, building xterm fails like this.

---------------------
target: xterm.compile
---------------------
...
/opt/OSELAS.Toolchain-2012.12.1/arm-cortexa9-linux-gnueabihf/gcc-4.7.3-glibc-2.16.0-binutils-2.22-kernel-3.6-sanitized/bin/../lib/gcc/arm-cortexa9-linux-gnueabihf/4.7.3/../../../../arm-cortexa9-linux-gnueabihf/bin/ld: main.o: undefined reference to symbol 'IceSetIOErrorHandler'

/home/richard/git/DistroKit/platform-pengutronix-beagleboneti/sysroot-target/usr/lib/libICE.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status

The library seems to be okay:

file /home/richard/git/DistroKit/platform-pengutronix-beagleboneti/sysroot-target/usr/lib/libICE.so.6.3.0 
/home/richard/git/DistroKit/platform-pengutronix-beagleboneti/sysroot-target/usr/lib/libICE.so.6.3.0: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped

Any ideas?

Thanks,
Richard

Try:

PTXCONF_TARGET_EXTRA_LDFLAGS="-Wl,--copy-dt-needed-entries"

In the platformconfig.

That does fix the build, but I think it isn't the right way. This is
not a problem with the tool chain. Rather, it is really a bug in the
xterm build scripts, strictly speaking. [1]

So I think the best way would be to patch the xterm package itself.
Failing that, then the ldflag, being a work around, should go into
rules/xterm.make.

Do you agree?

Thanks,
Richard

Some time ago you wrote:

   http://thread.gmane.org/gmane.comp.embedded.ptxdist.devel/10780/focus=10781

Isn't that the better way?

[ptxdist] [PATCH] xterm: fix the build

[Richard Cochran]

Due to the change in the way that gcc is resolving the DSO linking,
shared libraries must now be named explicitly. As a result, the configure
script in the xterm package does not find libICE as it should. This patch
works around the problem by adding that library manually.
