Hi, I think the build is unable to verify that samba provides smbc_set_context and smbc_option_set because it can't find the definition for `struct timespec`. Here is an excerpt from CMakeError.log:
``` Determining if the smbc_set_context exist failed with the following output: Change Dir: /build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp Run Build Command:"/usr/bin/make" "cmTC_3c66e/fast" make[3]: Entering directory '/build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp' /usr/bin/make -f CMakeFiles/cmTC_3c66e.dir/build.make CMakeFiles/cmTC_3c66e.dir/build make[4]: Entering directory '/build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp' Building C object CMakeFiles/cmTC_3c66e.dir/CheckSymbolExists.c.o /usr/bin/cc -I/usr/include/samba-4.0 -g -O2 -fdebug-prefix-map=/build/kde-runtime-7OuCXd/kde-runtime-17.08.3=. -fstack-protector-strong -Wformat -We rror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -Wdate-time -D_FORTIFY_SOURCE=2 -Wno-long-long -std=iso9899:1990 -Wundef -Wcast-align -Werror-imp licit-function-declaration -Wchar-subscripts -Wall -W -Wpointer-arith -Wwrite-strings -Wformat-security -Wmissing-format-attribute -fno-common -o C MakeFiles/cmTC_3c66e.dir/CheckSymbolExists.c.o -c /build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp/CheckSymbol Exists.c In file included from /build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp/CheckSymbolExists.c:2: /usr/include/samba-4.0/libsmbclient.h:168:18: error: field ‘btime_ts’ has incomplete type struct timespec btime_ts; ^~~~~~~~ /usr/include/samba-4.0/libsmbclient.h:172:18: error: field ‘mtime_ts’ has incomplete type struct timespec mtime_ts; ^~~~~~~~ /usr/include/samba-4.0/libsmbclient.h:176:18: error: field ‘atime_ts’ has incomplete type struct timespec atime_ts; ^~~~~~~~ /usr/include/samba-4.0/libsmbclient.h:180:18: error: field ‘ctime_ts’ has incomplete type struct timespec ctime_ts; ^~~~~~~~ /usr/include/samba-4.0/libsmbclient.h:1117:38: warning: ‘struct timeval’ declared inside parameter list will not be visible outside of this definition or declaration struct timeval *tbuf); ^~~~~~~ /usr/include/samba-4.0/libsmbclient.h:1936:41: warning: ‘struct timeval’ declared inside parameter list will not be visible outside of this definition or declaration int smbc_utimes(const char *url, struct timeval *tbuf); ^~~~~~~ make[4]: *** [CMakeFiles/cmTC_3c66e.dir/build.make:66: CMakeFiles/cmTC_3c66e.dir/CheckSymbolExists.c.o] Error 1 make[4]: Leaving directory '/build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp' make[3]: *** [Makefile:121: cmTC_3c66e/fast] Error 2 make[3]: Leaving directory '/build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp' File /build/kde-runtime-7OuCXd/kde-runtime-17.08.3/obj-x86_64-linux-gnu/CMakeFiles/CMakeTmp/CheckSymbolExists.c: /* */ #include <libsmbclient.h> int main(int argc, char** argv) { (void)argv; #ifndef smbc_set_context return ((int*)(&smbc_set_context))[argc]; #else (void)argc; return 0; #endif } ``` I don't know how to fix this, though. -- Matt
