Prior to this commit, builds of `pkgsCross.*.gpsd` were failing.
`gpsd` expects `CCVERSION` to be set, and fails if it is not set.
Scons does not guarantee that `CCVERSION` will be set, nor does it
specify under what circumstances it will or will not be set: "This may
or may not be set, depending on the specific C compiler being used."
https://scons.org/doc/production/HTML/scons-man.html#cv-CCVERSION
Apparently cross-compilation triggers one of those unspecified
circumstances. There are several bug reports to scons relating to
this:
https://github.com/SCons/scons/issues/1723
https://github.com/SCons/scons/issues?q=is%3Aissue+ccversion+is%3Aclosed
`gpsd` does not use `CCVERSION` for any purpose other than printing a
log message at the start of the build:
d055863603
This commit modifies the log message, replacing `env['CCVERSION']`
with `env['CC']`, since `CC` is always set when using nixpkgs'
standard builder.
With this commit, `pkgsCross.mips64el-linux-gnuabi64.gpsd` and
`pkgsCross.powernv.gpsd` build correctly on x86_64. Prior to this
commit, they would fail with:

longDescription = ''
|
|
gpsd is a service daemon that monitors one or more GPSes or AIS
|
|
receivers attached to a host computer through serial or USB ports,
|
|
making all data on the location/course/velocity of the sensors
|
|
available to be queried on TCP port 2947 of the host computer. With
|
|
gpsd, multiple location-aware client applications (such as navigational
|
|
and wardriving software) can share access to receivers without
|
|
contention or loss of data. Also, gpsd responds to queries with a
|
|
format that is substantially easier to parse than the NMEA 0183 emitted
|
|
by most GPSes. The gpsd distribution includes a linkable C service
|
|
library, a C++ wrapper class, and a Python module that developers of
|
|
gpsd-aware applications can use to encapsulate all communication with
|
|
gpsd. Third-party client bindings for Java and Perl also exist.
|
|
|
|
Besides gpsd itself, the project provides auxiliary tools for
|
|
diagnostic monitoring and profiling of receivers and feeding
|
|
location-aware applications GPS/AIS logs for diagnostic purposes.
