Go build fails because of -j1 flag despite use_parallel_build no

[TruePath (Peter Gerdes)]

On the latest macports (build from master at commit e641f42a) attempts to install go fail with the error given below because make.bash doesn't like the -j1 option

This can be solved via the quick hack of changing the build.cmd in the portfile to build.cmd bash -c "./make.bash" but this is an ugly hack. The docs don't say that -j1 will be passed if use_parrallel_build is set to no but there should be some way to suppress this so no weird shim to eliminate the -j1 arg is needed (I'm sure I just don't know how to do it)

Ohh sorry, this is on OS X 11.4 Xcode 12.5, Build version 12E262 installing go 1.16.4

This is a consequence of [d148e62c89c0fee07e202dd64b132e6134e7537e/macports-base]. Clearing build.jobs should work around the issue I think.

And this seems to have been fixed already in [1d7be07f3f1c1404c50e503d8ef25360616b50b1/macports-ports]?

The check here

​https://github.com/macports/macports-base/blob/d148e62c89c0fee07e202dd64b132e6134e7537e/src/port1.0/portbuild.tcl#L175

is I believe supposed to catch build systems that are not known to support the -j option, but clearly fails in this case as the custom build script matches *make*. Maybe that check should be made more robust, so somehow make sure it only matches the make, ninja and scons build commands ?

@TruePath, can you confirm this is still happening? A fix was added as @jmroot has mentioned. Most recent version of Go built fine on all platforms: ​https://ports.macports.org/port/go/builds

[herbygillot (Herby Gillot)]

This has been fixed by setting build.jobs to -1: ​https://github.com/macports/macports-ports/blob/ddde86ffdf1dc377346bc1808f74360d321cf76c/lang/go/Portfile#L88
