From 3835899b3b29904eede98e0c22973a430c9cb1f9 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Sat, 24 Nov 2012 23:26:09 -0800 Subject: ubi-tests: fix pthreads linking Technically, '-l' linker options should be included only after the objects which must link to the library. So when we include '-lpthread' in the LDFLAGS variable, it gets placed too early (i.e., before the io_paral.o object), and so the pthread linkage never occurs. The following error probably only shows up with linkers that don't link pthreads by default. $ make tests V=1 ... gcc -I../../ubi-utils//include -I ../../include -lpthread -Wall -Wextra -Wwrite-strings -Wno-sign-compare -ffunction-sections -fdata-sections -Wl,--gc-sections -g -o /home/norris/git/mtd-utils/tests/ubi-tests/io_paral /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.o /home/norris/git/mtd-utils/tests/ubi-tests/helpers.o libubi.a /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.o: In function `main': /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:287: undefined reference to `pthread_create' /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:295: undefined reference to `pthread_create' /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:303: undefined reference to `pthread_join' collect2: ld returned 1 exit status make[2]: *** [/home/norris/git/mtd-utils/tests/ubi-tests/io_paral] Error 1 ... $ ld --version GNU ld (GNU Binutils for Ubuntu) 2.22 ... $ gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 ...
