From: Esen Sagynov Date: 2010-10-13T19:11:35+09:00 Subject: Cannot install a gem on Windows x64 Hi, I am trying to install CUBRID Database Driver through "gem install cubrid" on my Windows x64 machine. 1. I have installed CUBRID 3.0 x64. 2. Ruby 1.8.7-p302 from http://rubyinstaller.org/downloads/ 3. DevKit-3.4.5-20100819-1535-sfx.exe from http://rubyinstaller.org/downloads/ In the gem's extconf.rb, there is a line which checks if there is a "cascci" library like "if have_library("cascci", "cci_init")". The path to cascci library is correctly set in "C:/CUBRID/lib", include files are in "C:/CUBRID/include". However, when I install cubrid gem using "gem install cubrid", or when I compile it using "ruby extconf.rb" I got the following error: ------------------------------------------------ checking for cci_init() in -lcascci... no cascci could not be found. Either you have not installed CUBRID Database yet or the path to CUBRID is not set. *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. ------------------------------------------------ have_library: checking for cci_init() in -lcascci... --------- no "gcc -o conftest -I. -IC:/Ruby/lib/ruby/1.8/i386-mingw32 -I. -IC:/CUBRID/include -g -O2 -DFD_SETSIZE=256 conftest.c -L. -LC:/Ruby/lib -LC:/CUBRID/lib -L. -lmsvcrt-ruby18-static -lcascci -lshell32 -lws2_32 " checked program was: /* begin */ 1: #include 2: #include 3: #include 4: 5: /*top*/ 6: int main() { return 0; } 7: int t() { void ((*volatile p)()); p = (void ((*)()))cci_init; return 0; } /* end */ "gcc -o conftest -I. -IC:/Ruby/lib/ruby/1.8/i386-mingw32 -I. -IC:/CUBRID/include -g -O2 -DFD_SETSIZE=256 conftest.c -L. -LC:/Ruby/lib -LC:/CUBRID/lib -L. -lmsvcrt-ruby18-static -lcascci -lshell32 -lws2_32 " checked program was: /* begin */ 1: /*top*/ 2: int main() { return 0; } 3: int t() { cci_init(); return 0; } /* end */ -------------------- I checked the path, it is correct, CUBRID is installed. I have successfully installed both through gem and through manual compilation the same cubrid gem on Windows 32 bit. But on x64 it fails. How should I compile the gem under Windows x64? Should I have some libraries for it? Why rubygem cannot find the library in x64? I suppose some flags should be present to indicate that this is x64 machine. Or is there anything else I should know? Any help would be highly appreciated. Thank you in advance! -- Posted via http://www.ruby-forum.com/.
