Subject:	cygport bug on installl
X-IsSubscribed:	yes

Hi Yaakov,
just found a curious bug on cygport during install phase.

during the install phase the expected behavior is

--------------------------------
Fixing symlinks:
Fixing libtool modules:
Stripping executables:
         usr/bin/cygglpk-36.dll
         usr/bin/glpsol.exe
Preparing debuginfo source files:
         145 files
Preparing executables for UAC:
---------------------------------

However if the first level directory is a symlink

$ ls -l /pub
lrwxrwxrwx 1 marco Administrators 19 Jun 26 19:07 /pub -> 
/cygdrive/e/cyg_pub

the install phase never complete.
 From debug I see a that the dlname test fails as
the left term expands the symlink but the left term does not.

+ '[' /cygdrive/e/cyg_pub/devel/glpk/32bit/prova '!=' 
/pub/devel/glpk/32bit/prova/glpk-4.54-1/inst/usr ']'
+ dlname=../../../../../bin/cygglpk-36.dll
++ readlink -f usr/lib/../../../../..
++ __host_prefix
++ local prefix sysroot
++ inherited cross
++ local class
++ local classname
++ for class in '"$@"'
++ classname=cross
++ defined _cross_CYGCLASS_
++ ((  1 != 1  ))
++ '[' -n '' ']'
++ return 1
++ return 1
++ sysroot=
++ case ${CHOST} in
++ prefix=/usr
++ echo -n /usr
+ '[' /cygdrive/e/cyg_pub/devel/glpk/32bit '!=' 
/pub/devel/glpk/32bit/prova/glpk-4.54-1/inst/usr ']'
+ dlname=../../../../../../bin/cygglpk-36.dll
++ readlink -f usr/lib/../../../../../..

and go on...

Regards
Marco
