[asterisk-bugs] [JIRA] (ASTERISK-25289) Build System does not respect CFLAGS and CXXFLAGS when building menuselect

Alexander Traud commented on ASTERISK-25289:
--------------------------------------------

[~abelbeck], which CFLAGS are you using exactly?{noformat}make menuselect.makeopts
menuselect/menuselect --disable BUILD_NATIVE{noformat}When cross-compiling, didn’t you make Menuselect? I am curious, because an undefined value for AST_NATIVE_ARCH should have broken your Menuselect. I wonder whether AST_NATIVE_ARCH=0 works in your case as well.

The Asterisk team has problems to follow-up on comments to already closed reports. Why ever. One solution is to go for the ‘Retriage Issue’ button at the top when you logged into Jira. However, I am not sure whether all members get that button. Therefore, another approach is to report a new issue. Then, via the ‘More’ button, you link this report here as ‘caused by'. I am not able to do this on behalf of you or the team, therefore I can only suggest that. This is no devaluation of your report, quite the contrary, this suggestion is about speeding up the inclusion of your suggestion.

Furthermore, if feasible, please attach a patch created via {{diff -u}}, after you created the new report, again via the button ‘More’. That eases to understand where in code (when exactly) you want to test for the shell environment variable [cross_compiling|https://www.gnu.org/software/autoconf/manual/html_node/Runtime.html]. For example, I guess you meant ‘… whether to set AST_NATIVE_ARCH=1’, so that test should come before {noformat}if $(${CC} -march=native …{noformat}

> GCC added sanitizers at 4.8. I'm attempting to build Asterisk with the UBsan (undefined behavior) and Asan (address) sanitizers enabled. UBsan is enabled with `-fsanitize=undefined`, and Asan is enabled with `-fsanitize=address`. (UBasan and Asan are mutually exclusive, so we repeat the steps below twice).
> localhost asterisk-13.4.0]$ export CFLAGS=-fsanitize=undefined
> localhost asterisk-13.4.0]$ export CXXFLAGS=-fsanitize=undefined
> localhost asterisk-13.4.0]$ ./configure

> Looking at the config.log, it appears the CFLAGS and CXXFLAGS were tested and accepted. Then:
