- GCC version 4.7 or later is required to build Julia.
- To use external shared libraries not in the system library search path, set
- Instead of setting
LDFLAGS, putting the library directory into the environment variable
LD_LIBRARY_PATH(at both compile and run time) also works.
USE_SYSTEM_*flags should be used with caution. These are meant only for troubleshooting, porting, and packaging, where package maintainers work closely with the Julia developers to make sure that Julia is built correctly. Production use cases should use the officially provided binaries. Issues arising from the use of these flags will generally not be accepted.
- See also the external dependencies.
Julia can be built for a non-generic architecture by configuring the
ARCH Makefile variable in a
Make.user file. See the appropriate section of
Make.inc for additional customization options, such as
For example, to build for Pentium 4, set
MARCH=pentium4 and install the necessary system libraries for linking. On Ubuntu, these may include lib32gfortran-6-dev, lib32gcc1, and lib32stdc++6, among others.
You can also set
Make.user for a maximum-performance build customized for the current machine CPU.
