cannot find -lteec #97

Closed B1nd00 closed 2 years ago

B1nd00 commented 2 years ago

I'm building op-tee on qemu with Armv8 and I've built optee_os and optee_client. I'm unable to make the example files as it returns the error cannot find -lteec.

This is what I do before make export HOST_CROSS_COMPILE=/User_data/home/nramu/optee-qemuv8-3.14.0/toolchains/aarch64/bin/aarch64-linux-gnu- export TA_CROSS_COMPILE=/User_data/home/nramu/optee-qemuv8-3.14.0/toolchains/aarch32/bin/arm-linux-gnueabihf- export TEEC_EXPORT=/User_data/home/nramu/optee-qemuv8-3.14.0/optee_client/out/export export TA_DEV_KIT_DIR=/User_data/home/nramu/optee-qemuv8-3.14.0/optee_os/out/arm/export-ta_arm32/

And this is my error image

If I do the make individually, the ta compiles not the host

Looking a acipher/host/Makefile, your should get -L$(TEEC_EXPORT)/lib next to -lteec at linker invocation.

LDADD += -lteec -L$(TEEC_EXPORT)/lib
(...)
$(BINARY): $(OBJS)
    $(CC) $(LDFLAGS) -o $@ $< $(LDADD)

Maybe try to add some traces in the Makefile to understand which arguments are passed to gcc.

I am getting that! It was the wrong image for the output. My bad
