[Mono-list] mono-build.sh fails (iconv troubles)

[Malte Hildingsson]

Building Mono from CVS with mono/doc/mono-build.sh currently fails if
"locate include/iconv.h" returns more than one hit. The error reveals
itself when mono/configure tries the C compiler for producing binaries
where it breaks and states:

error: C compiler cannot create executables

This occurs because of a bug in the handling of the location of iconv.
These steps general are from mono-build.sh:

[monocle@studpc74 monocle]$ locate include/iconv.h
/home/doozer/src/glibc-2.3.1/include/iconv.h
/usr/include/iconv.h
[monocle@studpc74 monocle]$ iconvh=`locate include/iconv.h`
[monocle@studpc74 monocle]$ echo $iconvh
/home/doozer/src/glibc-2.3.1/include/iconv.h /usr/include/iconv.h
[monocle@studpc74 monocle]$ iconvh_dir=`dirname $iconvh`
dirname: too many arguments
Try `dirname --help' for more information.

The failure of dirname leaves $iconvh_dir (and thus also
$iconvlib_dir) empty, and generates the following compiler test:

gcc -I/home/monocle/install/include -I -DGC_LINUX_THREADS
-DMONO_USE_EXC_TABLES -D_GNU_SOURCE -D_REENTRANT -fexceptions
-L/home/monocle/install/lib -L conftest.c >&5

And of course, the "-I " and "-L conftest.c" there doesn't produce the
expected result:

gcc: no input files

While this is easily fixed I thought perhaps it was not the preferred
outcome. :)
