1 /* Kernel-side additional module for the VxWorks threading support
2 logic for GCC. Written 2002 by Zack Weinberg.
4 This file is distributed with GCC, but it is not part of GCC.
5 The contents of this file are in the public domain. */
7 /* If you are using the Tornado IDE, copy this file to
8 $WIND_BASE/target/config/comps/src/gthread_supp.c. Then create a
9 file named 10comp_gthread_supp.cdf in target/config/comps/vxWorks
10 with the following contents:
12 Component INCLUDE_GCC_GTHREAD {
13 NAME GCC 3.x gthread support (required by C++)
14 CONFIGLETTES gthread_supp.c
15 REQUIRES INCLUDE_CPLUS
16 INCLUDE_WHEN INCLUDE_CPLUS
17 _FOLDER FOLDER_CPLUS
20 If you are using command line builds, instead copy this file to
21 $WIND_BASE/target/src/config/gthread_supp.c, and add the following
22 block to target/src/config/usrExtra.c:
24 #ifdef INCLUDE_CPLUS
25 #include "../../src/config/gthread_supp.c"
26 #endif
