Hello to all developers, following the arrival of GCC 8.x, I began to address the build key update in TQt. See the patch that was pushed for GCC 7.x: https://mirror.git.trinitydesktop.org/cgit/tqt3/commit/?id=71d8f1c4 Now I noticed that starting with GCC7, the compiler reports the version in a different way. Previously, gcc -dumpversion returned for example: 6.3.0. Now, regardless of the specific version of GCC 7.x or 8.x, it simply return: 7 or 8. Because the binary programs are compatible, the expression "7.*|6.*|5.*| 4.*)" in the configuration assured that for the GCC from 4.x to 6.x the build key was generated as follows: #define TQT_BUILD_KEY "x86_64 Linux g++-4.* full-config" But the gcc -dumpversion behavior change in GCC >= 7 has caused that the expression in the configuration not to be applied to GCC versions >= 7 and the build key is generated as follows: #define TQT_BUILD_KEY "x86_64 Linux g++-7 full-config" I believe that when binary programs are still compatible, we want to keep the build key identical (x86_64 Linux g++-4.* full-config), and I suggest modifying the expression in the configuration as follows: --- a/configure +++ b/configure @@ -2818,7 +2818,7 @@ g++*) 3.*) COMPILER_VERSION="3.*" ;; - 7.*|6.*|5.*|4.*) + [7-8]|[4-6].*) COMPILER_VERSION="4.*" ;; *) Please, what is your opinion? Cheers
