ccache 4.0 command execution failed while executing "system {*}$notty {*}$nice $fullcmdstring"

[thetrial (alabay)]

ccache-4.0 seems not to build under 10.11:

It is not clear what the reporter's exact issue is; need to provide main.log.

Maybe the reporter's issue is the same one encountered by the macOS 10.8-10.11 builders (errors involving AVX intrinsics—which clang 9.0 used on macOS 10.6-10.7 recognize, and could indicate code that won't run on older CPUs):

Software usually needs to do a bit of testing to see if a certain feature like __attribute__(target) is supported before using it, for example something like what is done here <​https://github.com/inikep/lzbench/blob/master/libdeflate/compiler_gcc.h>.

I've filed some upstream bug reports:

Build failure on 10.12: ​https://github.com/ccache/ccache/issues/688 See #61349
Build failure on 10.8-10.11: ​https://github.com/ccache/ccache/issues/689

[ryandesign (Ryan Carsten Schmidt)]

In 3a4f5058b038871a8741e89266183f88298e7e89/macports-ports (master):

ccache: Blacklist clang < 900

Temporary workaround to fix build on 10.8-10.11.

See: #61347

[thetrial (alabay)]

Now it ran through, thank you.

[ryandesign (Ryan Carsten Schmidt)]

ccache 4.1 now builds without modifications on 10.10 and later, and on 10.9 and earlier prints a more helpful message that the compiler is too old.

[ryandesign (Ryan Carsten Schmidt)]

In b4438723077c7600e8fd6cb4e6875dc0b0004bb7/macports-ports (master):

ccache: Blacklist clang < 700

Closes: #61347
