Can't build project

[leiradel]

Hi, I needed some stdlib functions for my Circle project and was directed here. My project was building with Circle (before I added the stdlib functions), but now it refuses to build.

$ make -j6
/home/leiradel/Develop/circle-stdlib/install/aarch64-none-circle/../../libs/circle/Rules.mk:74: *** RASPPI must be set to 3 or 4.  Stop.

I've tried some things to specify RASPPI=3 but none worked. My Makefile is

include ../../Config.mk

NEWLIB_ARCH = aarch64-none-circle
NEWLIBDIR = /home/leiradel/Develop/circle-stdlib/install/$(NEWLIB_ARCH)
CIRCLEHOME = $(NEWLIBDIR)/../../libs/circle

OBJS = \
    frontend/Main.o frontend/Audio.o frontend/Video.o frontend/Fifo.o \
    core/main.o \
    speex/resample.o \
    lrcpp/src/Components.o lrcpp/src/Core.o lrcpp/src/CoreFsm.o lrcpp/src/Frontend.o

include $(CIRCLEHOME)/Rules.mk

CFLAGS += -I$(NEWLIBDIR)/include -I$(STDDEF_INCPATH) -I$(NEWLIBDIR)/../../include
LIBS := $(NEWLIBDIR)/lib/libm.a $(NEWLIBDIR)/lib/libc.a $(NEWLIBDIR)/lib/libcirclenewlib.a \
    $(CIRCLEHOME)/addon/vc4/sound/libvchiqsound.a \
    $(CIRCLEHOME)/addon/vc4/vchiq/libvchiq.a \
    $(CIRCLEHOME)/addon/linux/liblinuxemu.a \
    $(CIRCLEHOME)/lib/sched/libsched.a \
    $(CIRCLEHOME)/lib/libcircle.a

This is likely an issue with my project, but I have no other place to ask.

Thanks in advance.

Have you called ./configure from circle-stdlib root? This script creates two Config.mk files, one in circle-stdlib root and one in libs/circle. The one in circle-stdlib root will be included by the first statement in your project's Makefile. The second will be read from Rules.mk, which is included into the Makefile too.

This error message comes from Rules.mk, which expects the RASPPI variable set to 3 or 4 for AArch64 operation in libs/circle/Config.mk. This is normally also written by the configure script. It is unusual to define NEWLIB_ARCH in the project's Makefile. It is written by the configure script to Config.mk in circle-stdlib root.

Have you called ./configure from circle-stdlib root?

Yes, I've called:

$ ./configure --prefix=aarch64-linux-gnu-
$ make RASPPI=3

It built successfully, it's just when I try to build my project that it complains about RASPPI not being set.

You should specify the desired Rasperry Pi model as an argument to the configure script, e.g.:

./configure --prefix=aarch64-linux-gnu- -r 3
make

Did you try that?

[leiradel]

Did you try that?

Thanks, that did the trick, I used make RASPPI=3 when it didn't work.

Now I'm getting one duplicated symbol and a bunch of missing symbols:

Any idea how to fix those?

This is odd, because in the normal Circle configuration for circle-stdlib with C++ support the macro STDLIB_SUPPORT has the value 3. With this setting there is no symbol vsnprintf in addon/linux/sprintf.cpp, but your build log says there are multiple definitions of it with one in addon/linux/sprintf.cpp. Please cleanup everything and configure and build again:

# from circle-stdlib root:
make mrproper

# these directories must be built and cleaned manually
cd libs/circle/addon/linux
make clean
cd ../vc4
./makeall clean
cd ../../../..

./configure -r 3 -p aarch64-linux-gnu-
make -j

cd libs/circle/addon/linux
make
cd ../vc4
./makeall --nosample -j
cd ../../../..

# now clean and build your own project

BTW. We are using the toolchain for the bare-metal target aarch64-none-elf-. Please see the Prerequisites section in README.md for a link. I do not know, if the aarch64-linux-gnu toolchain will work in all cases.

BTW. We are using the toolchain for the bare-metal target aarch64-none-elf-

That may be the issue. I'll install that toolchain and try again. Thanks for the tip.

Closing because no further feedback arrived.
