[Bug c/41128] New: ld: cannot find -luser32 problem

[justineuro at yahoo dot com]

The command line input

$ gcc max_memory.c -o max_memory.exe

currently gives

/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot
find -luser32
collect2: ld returned 1 exit status

The command worked fine initially.  Any suggestion as to correcting error would
be greatly appreciated.  Thanks in advance!

This is a bug in your installation of GCC and cygwin.

Thanks for the reply.  I have since re-installed and subsequently got an
"undefined reference to _WinMain@16' error".  It turns out I had to add the
-shared option, i.e., use the command line "gcc -shared -o file.exe file.c".  I
got this solution from url:
http://forums.sun.com/thread.jspa?threadID=5305805&messageID=10359759.  All is
fine now.  Again thanks!

Justine

Make sure you use the option -shared and ***NOT*** -share.  The -share option
when used in a windows command prompt shell in my machine ERASES the existing
*.exe files of the same name!!! However, it does give a message to the effect
that -share is not a valid option.  ---Justine
