You are probably seeing a classpath issue. My solution was to make the following change to environ.cc in the cygwin sources: This allows me to set the classpath and such in a shell script to a reasonable value, without having to jump through any cygpath hoops. Just for what it's worth. BTW, the first part is just #defines because I couldn't bring myself to type all the stuff you need for a variable. Eventually, I'd like to come up with a patch to allow the user to specify environment variables for translation, but I haven't had time to finish that yet. The only thing you really need for java is classpath. The others I added are INCLUDE and LIB (msvc++), and PYTHONPATH (omniorb). Rich This patch is hereby placed into the public domain. Anyone who wants it can have it. - - - - - - - - - - - - - - CUT HERE - - - - - - - - - - - - - - - Index: environ.cc =================================================================== RCS file: /cvs/src/src/winsup/cygwin/environ.cc,v retrieving revision 1.78 diff -u -r1.78 environ.cc --- environ.cc 21 Jun 2002 05:01:16 -0000 1.78 +++ environ.cc 24 Jun 2002 05:23:36 -0000 @@ -46,6 +46,29 @@ <= CYGWIN_VERSION_DLL_MALLOC_ENV) #define NL(x) x, (sizeof (x) - 1) +#define LIST_CONV(x) \ + { \ + x##"=",\ + sizeof(x),\ + NULL,\ + NULL,\ + cygwin_win32_to_posix_path_list,\ + cygwin_posix_to_win32_path_list,\ + cygwin_win32_to_posix_path_list_buf_size,\ + cygwin_posix_to_win32_path_list_buf_size\ + } +#define PATH_CONV(x) \ + { \ + x##"=",\ + sizeof(x),\ + NULL,\ + NULL,\ + cygwin_conv_to_full_posix_path,\ + cygwin_conv_to_full_win32_path,\ + return_MAX_PATH,\ + return_MAX_PATH \ + } + /* List of names which are converted from dos to unix on the way in and back again on the way out. @@ -55,20 +78,16 @@ static int return_MAX_PATH (const char *) {return MAX_PATH;} static NO_COPY win_env conv_envvars[] = { - {NL ("PATH="), NULL, NULL, cygwin_win32_to_posix_path_list, - cygwin_posix_to_win32_path_list, - cygwin_win32_to_posix_path_list_buf_size, - cygwin_posix_to_win32_path_list_buf_size}, - {NL ("HOME="), NULL, NULL, cygwin_conv_to_full_posix_path, - cygwin_conv_to_full_win32_path, return_MAX_PATH, return_MAX_PATH}, - {NL ("LD_LIBRARY_PATH="), NULL, NULL, cygwin_conv_to_full_posix_path, - cygwin_conv_to_full_win32_path, return_MAX_PATH, return_MAX_PATH}, - {NL ("TMPDIR="), NULL, NULL, cygwin_conv_to_full_posix_path, - cygwin_conv_to_full_win32_path, return_MAX_PATH, return_MAX_PATH}, - {NL ("TMP="), NULL, NULL, cygwin_conv_to_full_posix_path, - cygwin_conv_to_full_win32_path, return_MAX_PATH, return_MAX_PATH}, - {NL ("TEMP="), NULL, NULL, cygwin_conv_to_full_posix_path, - cygwin_conv_to_full_win32_path, return_MAX_PATH, return_MAX_PATH}, + LIST_CONV("PATH"), + PATH_CONV("HOME"), + LIST_CONV("LD_LIBRARY_PATH"), + PATH_CONV("TMPDIR"), + PATH_CONV("TMP"), + PATH_CONV("TEMP"), + LIST_CONV("INCLUDE"), + LIST_CONV("LIB"), + LIST_CONV("CLASSPATH"), + LIST_CONV("PYTHONPATH"), {NULL, 0, NULL, NULL, NULL, NULL, 0, 0} }; - - - - - - - - - - - - - - CUT HERE - - - - - - - - - - - - - - - On Fri, Jun 21, 2002 at 07:20:45PM +0200, Istvan Kurucz (ETH) wrote: > Hi, > > I've been using Cygwin for a long time but I'm not able to run Java > applications.
