My guess is this is related to how GoogleMock & GoogleTest are built (see details below), but unfortunately there is not much information about the best way of using these libraries in Ubuntu http://stackoverflow.com/questions/30865653/pthread-related-errors-when-upgrading-test-from-googletest-to-googlemock-ubuntu 14. After reducing the code to a minimal representative example, what happens is: I replaced the GoogleTest headers with the GoogleMock ones, as well as the "main" function: // Declarations at foo.h class Foo { public: int sum(int a, int b); // it returns a+b (defined in foo.cpp) }; // Test code at foo.test.cpp #include // replaced #include "foo.h" TEST(Foo,ReturnsSumOfTwoNumbers){ Foo foo; ASSERT_EQ( foo.sum(2,8), 10 ); } TEST(Foo,ReturnsSumOfTwoIntegerNumbers){ Foo foo; ASSERT_EQ( 6,foo.sum(-2,8) ); } // main.cpp #include // replaced int main(int argc, char **argv) { ::testing::InitGoogleMock(&argc, argv); // replaced InitGoogleTest return RUN_ALL_TESTS(); } This works FINE. When I try to use a GoogleMock feature (e.g a matcher): // foo.test.cpp using ::testing::Eq; //... TEST(Foo,ReturnsSumOfTwoNumbers){ Foo foo; // replaced ASSERT_EQ ASSERT_THAT( foo.sum(2,8), Eq(10) ); } .. It crashes with the following error: [ FATAL ] /path/to/gmock-1.7.0/gtest/include/gtest/internal/gtest-port.h:1340:: pthread_mutex_lock(&mutex_)failed with error 22 Aborted (core dumped) Using other gmock features yielded similar errors. Build info: Ubuntu 14.04 gcc 4.8.2 gmock 1.7.0 is downloaded and built with CMAKE: wget https://googlemock.googlecode.com/files/gmock-1.7.0.zip unzip gmock-1.7.0.zip GMOCK_PATH=$PWD/gmock-1.7.0 GTEST_PATH=$GMOCK_PATH/gtest mkdir $GMOCK_PATH/lib $GTEST_PATH/lib pushd $GMOCK_PATH/lib cmake -DBUILD_SHARED_LIBS=ON .. make cd $GTEST_PATH/lib cmake -DBUILD_SHARED_LIBS=ON .. make popd Finally, the whole project is built using Qt's qmake: INCLUDEPATH += $${GMOCK_PATH}/incl

At some point my application crashes with the following error, terminate called pthread_mutex_lock &mutex failed after throwing an instance of 'odbc::SQLException' what(): [libodbc++]: OS error, mutex lock failed HY000 : [libodbc++]: OS error, mutex lock failed :: [Open DB] : IN DB /home/test/Users/Srini/xxxxxxx/dbnamexxx terminate called recursively HY000 : [libodbc++]: OS error, mutex lock failed :: [Open DB] : IN DB /home/test/Users/Srini/xxxxxxx/dbnamexxx terminate called recursively HY000 : [libodbc++]: OS error, mutex lock failed :: [Open DB] : IN DB /home/test/Users/Srini/xxxxxxx/dbnamexxx Aborted Seems the pthread_mutex_lock() in src/threads.cpp fails with error and libodbc throws exception and hence application crashes (running in my application in debug mode). I have checked the return value of pthread_mutex_lock() and it is EINVAL (22) which means Invalid Argument. The details of my setup is as follows, OS : Cent OS 5.3 libodbc++ : v0.2.3 unixODBC : v2.2.15pre MySQL Driver : v3.51.27 MySQL Server : v5.1.39 My odbcinst.ini file is as follows, -------------------8<---------------------- [ODBC] Trace = No Trace File = /tmp/sql.log Pooling = Yes [MySQL] Description = Driver = /usr/local/lib/libmyodbc3-3.51.27.so Driver64 = Setup = /usr/local/lib/libmyodbc3S-3.51.27.so Setup64 = UsageCount =1 CPTimeout =300 CPReuse =1 Threading =0 ------------------->8---------------------- My configure option for libodbc++ is as follows, ./configure --enable-static=yes --with-odbc=/home/path/to/unixodbc/unixODBC-2.2.15pre/DriverManager/.libs/ --enable-threads=yes I have also tested with libodbc++ v0.

Let me try to explain the setup of the program: There is a main thread which initializes a recursive mutex for use within (multiple) event threads running along the main thread, the mutex is used for (what a surprise) outlining a critical section. Here is a diagram (plaintext, ASCII-art): +------------------+ | main() thread | +------------------+ | ... | | initialize mutex | | ... | | spawn threads ---+-------------+------------------------+-------------// | ... | | | = = +------------------+ +------------------+ +------------------+ | event thread1 | | event thread2 | +------------------+ +------------------+ | ... | | ... | | lock mutex | | lock mutex | | | | | | unlock mutex | | unlock mutex | | ... | | ... | +------------------+ +------------------+ The mutex variable is declared globally and initialised in the main thread. ---(globally) pthread_mutex_t CritSec; --- The initialisation of the mutex is being done as follo
