[SOLVED] Qt Creator on OS X cannot find armadillo
Qt Creator 3.1.1 cannot find armadillo under OS X 10.9.3. I have installed armadillo 4.300.5 using the cmake install, and I have armadillo entries under /usr/include and libarmadillo in /usr/lib. When typing #include <a, Qt Creator suggests armadillo for autocomplete, meaning that Qt Creator indeed finds the lib. But trying to compile the program only gives the error
'armadillo' file not found
with a red ! on the #include line. Here is a MWE:
using namespace std;
TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt
SOURCES += main.cpp
LIBS += -larmadillo
I am using the default Desktop qt clang 64bit compiler option.
Thanks for any input!
Hi and welcome to devnet,
Did you try adding /usr/lib to the list of known folder ?
Where is that list located? I cannot find it in the Preferences of Qt Creator.
For you project:
@LIBS += -L/usr/lib@
Yes, I tried both the line you posted and also
@LIBS += -L/usr/lib -larmadillo@
I have also tried to right-click the project and select "Add Library...", but
I get the same error message.
If I do
@clang -O3 -o test -larmadillo main.cpp@
in the terminal it compiles just fine.
It seems I needed to add the includes directory,
@INCLUDEPATH += /usr/include@
Now it works =)
This is not yet solved...
I'm running on Ubuntu 14.04 with Qt Creator 3.1.0 (opensource)
on macOs add this to .pro
install armadillo: brew install armadillo
brew list armadillo
INCLUDEPATH += /usr/local/Cellar/armadillo/8.200.2/include/
LIBS += -L/usr/local/Cellar/armadillo/8.200.2/lib/ -larmadillo
