Well, the new glibc-2.4 only supports nptl, unlike glibc-2.3 which supported |
15 |
both threading models. So if you want legacy linuxthreads, you have to stay |
16 |
with glibc-2.3. |
17 |
As for being "better", glibc-2.4 is better than 2.3 IMHO. |
18 |
Also, "nptl -nptlonly" combination with 2.3 actually builds two versions of |
19 |
glibc, one with nptl and one with linuxthreads, so you get a longer compile |
20 |
and larger disk footprint. |
