The last diff had LTO_USE=3DGCC, but it should have be= en LTO_USE=3D gcc=3Dyes. Other new changes: - Return the option for the shared R library [1]. This performance hit described in the reference is one reason why the math/libR port should stick around, i.e., for the few ports that require an embedded R. - Create an option for memory profiling (like upstream, off by default). - Create an option for R profiling (like upstream, on by default). - --enable-BLAS-shlib when R's internal BLAS is chosen. P.S., Rainer, I've seen some old blog posts that show ATLAS can be faster. = Do you have any specific tests I can reproduce to gauge the current speedups u= sing ATLAS versus R's internal BLAS? ---------------------------------------- [1] From the R Installation and Administration Manual: "Flag --enable-R-shlib causes the make process to build R as a dynamic (sha= red) library, typically called libR.so, and link the main R executable R.bin aga= inst that library. This can only be done if all the code (including system libraries) can be compiled into a dynamic library, and there may be a performance47 penalty*. So you probably only want this if you will be using= an application which embeds R."
