Hello, Trying install libtool-2.4.6 on Solaris 11.3 x64. $ uname -a SunOS hidden 5.11 11.3 i86pc i386 i86pc To build 64 bit code libtool, such as $ ./configure CC='cc -m64' LD_LIBRARY_PATH_64 should be used instead of LD_LIBRARY_PATH. Sample patch is attached, although it does not have check for x64, sorry. Regards, --- Kiyoshi
