I came across a compile error that cannot find the function defined in a given file when I try to add SQLiteCpp source to my qt application. It cost me a half day and I hope some one can kindly help me. Thanks a lot!
1. build libSQLiteCpp.a and libsqlite3.a
{
get src:
git clone https://github.com/SRombauts/SQLiteCpp.git
cd SQLiteCpp
git submodule init
git submodule update
build libs:
cd /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/ \
&& . /opt/fsl-imx-x11/4.1.15-2.0.0/environment-setup-cortexa9hf-neon-poky-linux-gnueabi \
&& ./build.sh
}
2. edit qt app and its project file
{
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = sqltest
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
INCLUDEPATH += /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/include/
INCLUDEPATH += /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/include/SQLiteCpp/
INCLUDEPATH += /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/sqlite3/
LIBS += /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/sqlite3/libsqlite3.a
LIBS += /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/libSQLiteCpp.a
FORMS += mainwindow.ui
}
3. qt app cross compile error: can not find the function defined in sqlite3.c

}
4. more info
{
ocean@mhc:~/test/qt5_all/sqltest/sqltest$ grep -rns "sqlite3_libversion" /home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/SQLiteCpp_example1
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/SQLiteCpp_tests
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/sqlite3/libsqlite3.a
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/sqlite3/CMakeFiles/sqlite3.dir/sqlite3.c.o
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/libSQLiteCpp.a
/home/ocean/test/qt5_all/sqltest/XLIBS/SQLiteCpp/build/CMakeFiles/SQLiteCpp.dir/src/Database.cpp.o
}
Can somebody tell me why why XLIBS/SQLiteCpp/src/Column.cpp cannot read sqlite3_column_origin_name() from libsqlite3.a (sqlite3.c)? I have built XLIBS/SQLiteCpp/build/sqlite3/libsqlite3.a and then the XLIBS/SQLiteCpp/build/libSQLiteCpp.a !!
