Re: gEDA-user: GTKWave build problem

Hi,

Looks like an LD_LIBRARY_PATH problem to me. Keep in mind that LD_LIBRARY_PATH is a colon separated list of directories to search for `.so' (shared object libraries) files, when a program starts. Try to find the file `libiconv.so' on your system using `locate' and/or `find / -name libiconv.so\*'. Wait till it searches the whole file system, in case you have multiple versions installed. You could also try to paste the program into an editor and compile it yourself with the supplied command line, then run `ldd' on the resulting binary, this will list all the shared libraries that it wants to load, and where they can be found, or not found as the case may be.

Maybe you got me a little closer - I looked at the config.log for building GTKWave, here's what I found:

[root@PaulsLinux gtkwave-2.0.0pre3-20030319]# export LD_LIBRARY_PATH

sigh, to no avail, same message.

any thoughts? Maybe I need to learn how to handle the mysterious "prefix" stuff... paul

Hi folks, one more build hurdle and I'll be gEDA-ing! In running
configure for GTKWave, I get


[...]


checking for GTK - version >= 1.2.0... yes
checking for xml2-config... /usr/local/bin/xml2-config
checking for libxml - version >= 2.4.0... no


What probably happens is that xml2-config is called with flags such as
'--cflags' and '--ldflags'. These specify where the xml2 library has been
installed. You might check the config log to see what was returned, and if
in fact libxml2.* lives in the directory returned by 'xml2-config
--ldflags'.
