[swift-corelibs-dev] libdispatch build issue

[Dzianis Fedarenka]

Actually, I’ve built library on 14.04 but it required some hack’s like adding dummy #define and calling libtool with different arguments after make failed with errors.

First try:

user$ sudo apt-get install libblocksruntime-dev libkqueue-dev libpthread-workqueue-dev

libblocksruntime-dev is already the newest version.
libkqueue-dev is already the newest version.
libpthread-workqueue-dev is already the newest version.

user$ git clone https://github.com/apple/swift-corelibs-libdispatch && cd swift-corelibs-libdispatch
user$ sh autogen.sh
user$ ./configure --with-blocks-runtime
user$ make
queue.c:216:22: error: use of undeclared identifier 'WORKQ_BG_PRIOQUEUE'
                .dgq_wq_priority = WORKQ_BG_PRIOQUEUE,
                                   ^
queue.c:227:22: error: use of undeclared identifier 'WORKQ_BG_PRIOQUEUE'
                .dgq_wq_priority = WORKQ_BG_PRIOQUEUE,
                                   ^
queue.c:926:18: error: invalid application of 'sizeof' to an incomplete type 'struct dispatch_root_queue_context_s []'
        dispatch_assert(countof(_dispatch_root_queue_contexts) ==
        ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

queue.c:926:18: error: invalid application of 'sizeof' to an incomplete type 'struct dispatch_root_queue_context_s []'
        dispatch_assert(countof(_dispatch_root_queue_contexts) ==
                        ^
queue.c:926:18: error: invalid application of 'sizeof' to an incomplete type 'struct dispatch_root_queue_context_s []'

        dispatch_assert(countof(_dispatch_root_queue_contexts) ==
                        ^
5 warnings and 6 errors generated.


Second try (with manually defined WORKQ_BG_PRIOQUEUE macro ;)):
user$ make
/bin/bash ../libtool  --tag=CXX   --mode=link clang++  -g -O2 -avoid-version    -o libdispatch.la -rpath /usr/local/lib allocator.lo apply.lo benchmark.lo data.lo introspection.lo init.lo io.lo object.lo once.lo queue.lo semaphore.lo source.lo time.lo transform.lo voucher.lo shims/linux_stubs.lo     -lpthread  -Lyes -lBlocksRuntime
../libtool: line 6000: cd: yes: No such file or directory
libtool: link: cannot determine absolute directory name of `yes'
make[2]: *** [libdispatch.la] Error 1
make[2]: Leaving directory `/home/user/code/libs/tmp/swift-corelibs-libdispatch/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/user/code/libs/tmp/swift-corelibs-libdispatch/src'
make: *** [all-recursive] Error 1

Third try (after running libtool without -Lyes option):
user$ make
bsdtests.c:28:10: fatal error: 'crt_externs.h' file not found
#include <crt_externs.h>
         ^
1 error generated.


Few… At least libdispatch was built ;)
