Thanks to RP. However, most of the cross-toolchains support "static" linking as a default behaviour. Can we follow the same path? 37914 3 sgw 2013-10-14 20:21:05 +0000 Would documentation of this issue be sufficient? Depending on the use case most development environements will be using dynamic linking. I can see in the smaller footprints static linking might be useful, but that might be limited cases, we don't want to add the overhead of the static libraries to all the dev images (yet get quite large). 37919 4 maxin.baby.john 2013-10-15 08:09:58 +0000 (In reply to comment #3) > Would documentation of this issue be sufficient?

Yes. Not everyone needs static linking. Ideally, can we think of adding the minimum set of static libraries (libc, libc++) to the SDK ? Additional storage required for the static libraries are listed below (for arm): # du -h *.a 116K libanl.a 16K libBrokenLocale.a 4.0K libbsd-compat.a 17M libc.a 72K libc_nonshared.a 160K libcrypt.a 36K libdl.a 4.0K libg.a 4.0K libieee.a 2.3M libm.a 12K libmcheck.a 844K libnsl.a 1.7M libpthread.a 4.0K libpthread_nonshared.a 444K libresolv.a 228K librpcsvc.a 296K librt.a 9.7M libstdc++.a 784K libsupc++.a 36K libutil.a which is around 40M 38077 5 1571 maxin.baby.john 2013-10-21 09:11:36 +0000 Created attachment 1571 Documentation fix Added a Note about this in the adt manual. 38352 6 srifenbark 2013-10-31 15:07:37 +0000 Hi, I took your patch and hand-applied it. I did some technical writing on it so it is not verbatim. You can examine the note here: http://www.yoctoproject.org/docs/1.6/adt-manual/adt-manual.html#optionally-building-a-toolchain-installer. I flipped the "Documentation change" field to "Done". Let me know if the note works.
