How can i import LIBS

Yaldiz

HI,

I am using SDK's library (#include "libsoc_gpio.h")

And I also added theese to the .pro file;

QMAKE_CXXFLAGS += -lpthread
LIBS +=-lpthread

LIBS += -llibsoc_gpio

But when i compile the code it's gives theese errors;

1-) :-1: error: collect2: error: ld returned 1 exit status
2-) :-1: error: [Makefile:653: LCD-SubMenus] Error 1

NOTE: library path: /opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include

How can i use this?

Best regards.

@Yaldiz AFAIK, for Linux system, you should remove "lib" for the library name.
You can specify library path with -L

To summarize the correct way should be:

LIBS += -L/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include -lsoc_gpio

I tried for sqlite like below and it's works fine;

LIBS += -L/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include -lsqlite3

but when i try for libsoc_gpio it's gives same error.
I think there is another problem. What could be this problem?

Are you really sure /opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include contains the library file libsoc_gpio.so?

Yaldiz

Yes, exist libsoc_gpio.h

huseyin@X-X:/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include$ ls libsoc
libsoc_board.h libsoc_debug.h libsoc_i2c.h libsoc_pwm.h
libsoc_conffile.h libsoc_gpio.h libsocketcan.h libsoc_spi.h

This is the header file not the library which you want to link with.
The library will have .so (for dynamic library) or .a (for static library) as extension.

try this to find its location: find opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/ -name libsoc_gpio.*

libsoc_gpio.so

No .so or .a file.

Did you try the search it with:
find /opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/ -name libsoc_gpio.*
or
find /opt/tdx-xwayland/5.6.0/sysroots/ -name libsoc_gpio.*

Yaldiz

I tried 2 option, the .so or .a file does not exist.

How do you want to use a library which you don't have?
Check this with your SDK provider.

Yaldiz

Thank you very much for your time and help, I will ask my SDK provider.
