This way the system is happy with the installed gcc version not being replaced, and user and software can opt for newest built gcc as needed based on setting PATH and LD_LIBRARY_PATH properly. To make use of these new packages, simply prepend PATH and LD_LIBRARY_PATH so these new versions take affect over the system installed versions in /usr/bin and /usr/lib. In doing configure -prefix=/wherever_you_want_located allows you to place the package wherever you want.Ĭonfigure -help to list all options, specifically to see the -with-? that are available. Repeat for subsequent packages, specifying multiple -with-?=, then build gcc last. mpfr needs gmp so do it second using -with-gmp=/wherever/gmp-#. You can rsync from the EAOs night builds in Hilo if you want a 64-bit Linux or macOS build. I believe gmp needs nothing, do that first. Following the above as a template, download latest gmp, mpfr, and mpc, and build each of those from source first. If I try the configuration with -prefix=/usr/, the installation fails with the message:Ĭode: Select all download from gcc mirror Given the previous considerations, I also tried to make an installation so that the newer version does not sit along with the older one but that it actually replaces it. The final system set-up results in some programs using the old compiler version whereas others use the newer version, which leads to incompatibility problems. While it’s distributed only as a source archive, it can. If I remove the old compiler with yum, some of these applications simply fail. Grsync is a cross-platform application and has been successfully tested on the Microsoft Windows, Mac OS X and GNU/Linux operating systems. However, the issue is that some software packages ignore this information and still look for the gcc compiler at the default directories (/usr/bin, /usr/sbin, /bin and /sbin). Compiling code works fine and the OS takes the newer version as the default compiler. This operation worked smoothly but resulted in 2 installed C compilers. I installed gcc 4.8.5 with yum (it's in the /usr subdirectory) in order to build gcc 8.3.0 from source, which is installed at /usr/local if no directory is specified. A session will help you retain all the settings. I'm having a bit of trouble with my gcc compilers in CentOS 7. The GUI is fairly basic and does a nice job of separating basic options that you are likely to use most often with rsync and the advanced options that help you tweak and customize rsyncs behavior to suit your needs.
