Build-System Options
The following options can be used in LE 10.x+ to customise the build experience:
Name
Values
Default
Description
THREADCOUNT#,#%100%Maximum number of packages to build concurrently. On an 8-core system,
50% would build up to 4 packages at a time.ONELOGyes,nonoIf
yes, packages will not create individual logs in ${THREAD_CONTROL}/logs. If THREADCOUNT is 1 the default becomes ONELOG=yes in which case use ONELOG=no to ensure individual logs are created for each package.LOGCOMBINEalways,never,failalwaysDetermine under what circumstances package logs are written to
stdout. Using never and fail can slightly reduce IO.MTBOOKENDSyes,noyesAdds
<<< and >>> tags to the combined log output (to facilitate searching).DISABLE_COLORSyes,nonoControl whether build system output is colored or not.
MTCOLORSalways,never,autoautoIf
DISABLE_COLORS=yes this option controls how scripts/pkgbuilder.py progress and status information is colored. auto will disable colors when output is being redirected to a file (ie. not a terminal).MTVERBOSEyes,nonoOutput additional job state information to
stderr during the build.MTPROGRESSyes,nonoOutput real-time load, memory and in-progress job information to
stderr at 1-second intervalsMTDEBUGyes,nonoOutput detailed debug information to
${THREAD_CONTROL}/debug.logMTADDONBUILDyes,nonoIf
no, the build will end after the first failure. When building add-ons, we typically ignore individual package failures and continue building until all packages have been built (or failed).MTIMMEDIATEyes,nonoWhen
MTADDONBUILD=no and a package fails, the build can finish after all currently building packages have completed, or it can terminate those packages immediately. Allowing packages that are currently building to finish building can save time when restarting the build.MTINTERVAL#60System load information is captured at regular intervals in
${THREAD_CONTROL}/loadstats.AUTOREMOVEyes,nonoRemove source code directories during the build once the source code directory is not required.
Persistent Options
Options can be specified on the command line, or added to persistent "options" files located under the root folder of the buildsystem, e.g.
~/LibreELEC.tv/.libreelec/options or the users home folder, e.g. ~/.libreelec/options - if both files exist, home folder options trump root folder options. The following gives a fairly clean and comprehensive output while still allowing command-line overrides:1
LOGCOMBINE=${LOGCOMBINE:-never}
2
MTPROGRESS=${MTPROGRESS:-yes}
3
MTIMMEDIATE=${MTIMMEDIATE:-no}

Builder Name and Version
If you are bulding and sharing images via the LibreELEC forums it is good to include a custom "builder" name with your images. This allows the team to count the number of active installs using your images (we can share this info on request). Builder name also populates into
/etc/os-release and logfiles, which helps forum staff supporting users differentiate between official releases and community created images. It is also possible to set custom versioning. e.g.1
PROJECT=Generic ARCH=x86_64 BUILDER_NAME=yourname BUILDER_VERSION=123 make image
Copied!
It is also possible to set persistent
BUILDER_NAME and BUILDER_VERSION in "options" files.Debug Images
The build-system automatically strips debug symbols from most packages. To disable this and include debug symbols and common debugging packagess in the image, enable
DEBUG, e.g.1
PROJECT=Generic ARCH=x86_64 DEBUG=yes make image
Copied!
To also include valgrind:
1
PROJECT=Generic ARCH=x86_64 DEBUG=yes VALGRIND=yes make image
Copied!
Note: The resulting image will be considerably larger than normal. The default boot partition is 512MB, but debug images may exceed this and require a 1GB partition.
