@ -61,6 +61,14 @@ tuned to conserve memory with additional CXXFLAGS:
|
|||
|
||||
./configure CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768"

Alternatively, or in addition, debugging information can be skipped for compilation. The default compile flags are
|
||||
`-g -O2`, and can be changed with:
|
||||
|
||||
./configure CXXFLAGS="-O2"
|
||||
|
||||
Finally, clang (often less resource hungry) can be used instead of gcc, which is used by default:
|
||||
|
||||
./configure CXX=clang++ CC=clang
