Gcc compiler installation cygwin

A: Yes and no. The setup program understands command-line arguments which allow you to control its behavior and choose individual packages to install. While this provides some functionality similar to such tools as apt-get or yum it is not as full-featured as those package managers. A: The basic reason for not using a more full-featured package manager is that such a program would need full access to all of Cygwin's POSIX functionality. That is, however, difficult to provide in a Cygwin-free environment, such as exists on first installation.

Sometimes, you may face issues while running the command mentioned above. In such cases,instead of make -j4 , you might need to use make -j2 on older machines.

Alternatively, On newer machines, you might need to use make -j8. Once the make command has completed successfully, execute the 'make install' command to copy the compiled code to various locations. Set the path of the cygwin installation in PATH variable. It is not mandatory to have an IDE. You can also use simple editors available for your OS.

On Windows: You can use Notepad. Or You can download and use editors like Textpad. The tar xf step takes several minutes to finish, 20 minutes on my i7 laptop. Just leave it and wait for it to complete. This is the longest step. The -j4 option lets the build process spawn up to four child processes in parallel. The main downside is that it jumbles the output messages generated during the build process.

If your CPU has even more hardware threads, you can specify a higher number with -j. For comparison, I tried various numbers on a Xeon-based machine having 12 hardware threads, and got the following build times:. Be warned: I encountered a segmentation fault the first time I ran with -j4. Bad luck on my part. If that happens to you, running the same command a second time should allow the build process to finish successfully.
