Linux/WL1837MOD: My steps to build the WL18xx software, what's wrong?

Hi

1
I set all tools from "Setting up the Host Environment" (WL18xx WiFi Build Process, link processors.wiki.ti.com/.../WL18xx_WiFi_Build_Process, exseption is only lib32bz2-1.0.
The "sudo apt-get install lib32bz2-1.0" command does not find such packet.

I resolved this issue. For my Linux mint 18.2 based on ubuntu 16.04 the command must be  "$ sudo apt-get install libz1:i386 libncurses5:i386 libbz2-1.0:i386".

But this does not resolve the issue.  The "Makefile:98: *** Cannot find development files for any supported version of libnl. Stop." message remained still.

"$ ./build_wl18xx.sh init" execution came to the end also as earlier.

I am waiting for the help,

thanks

Hi

The additional information to the question.

I started the command:
lyudmila@lyudmila-linuxmint ~/wl8-build/build-utilites $ ./build_wl18xx.sh hostapd

At execution the report is often given:

Package libnl-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libnl-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libnl-3.0' found

There is "libnl-3-dev libnl-route-3-dev libnl-genl-3-dev" in my Linux mint 18.2 based on ubuntu 16.04,
But this does not resolve the issue.

How to install libnl-3.0 package? 32 bit or 64 bit?

thanks

Not sure, why you are seeing this error. On my Ubuntu 16.04LTS builds the builds went ok, for recent kernels with Linaro tool chain.

Did, you try building libnl for the target file system first?

$ ./build_wl18xx.sh libnl

Thanks

Hi Hari

1. Did, you try building libnl for the target file system first?

Yes, I started 2 commands:

$ ./build_wl18xx.sh libnl and ./build_wl18xx.sh update R8.7_SP3

No problem with libnl.

The problem is witth crda.

build_crda from function build_all() from build_wl18xx.sh  reports

"Makefile:98: *** Cannot find development files for any supported version of libnl.  Останов.
******  *******
Makefile:98: *** Cannot find development files for any supported version of libnl.  Останов.
****** ERROR 0 *******"

Thanks

Hi everybody

I found, that environment variables  are not transferred, though in the build_wl18xx.sh script they are set.

Here is the build_crda() function from the sbuild_wl18xx.sh script:

function build_crda()
{    
    cp `repo_path wireless_regdb`/regulatory.bin `path filesystem`/usr/lib/crda/regulatory.bin
    cp `repo_path crda`/pubkeys/* `path filesystem`/etc/wireless-regdb/pubkeys/
    cd_repo crda
    
    [ -z $NO_CLEAN ] && DESTDIR=`path filesystem` make clean
    [ -z $NO_CLEAN ] && assert_no_error
        PKG_CONFIG_LIBDIR="`path filesystem`/lib/pkgconfig" PKG_CONFIG_PATH="`path filesystem`/usr/local/ssl/lib/pkgconfig" DESTDIR=`path filesystem` CFLAGS+="-I`path filesystem`/usr/local/ssl/include -I`path filesystem`/include -L`path filesystem`/usr/local/ssl/lib -L`path filesystem`/lib" LDLIBS+=-lpthread V=1 USE_OPENSSL=1 make -j${PROCESSORS_NUMBER} all_noverify CC=${CROSS_COMPILE}gcc LD=${CROSS_COMPILE}ld AR=${CROSS_COMPILE}ar
    assert_no_error
        DESTDIR=`path filesystem` make install
        assert_no_error
    cd_back
}

I found this when I started the command ./build_wl18xx.sh crda. This command uses libnl-3-dev:amd64,  libnl-genl-3-dev:amd64 and gcc from my host  instead of CROSS_COMPILE=armv7l-timesys-linux-gnueabi-gcc and libnl32 from my ROOTFS ( from setup-env).

In what reason?  What's wrong?

thanks

Hi

Are there  some ideas?

thanks

Hi everybody

I defined that iw packet is not built too. I made experiments and I want to specify the reason.

"NL3xFOUND := $(shell $(PKG_CONFIG) --atleast-version=3.2 libnl-3.0 && echo Y)"   function from Makefile in iw folder does not find  libnl library, 

though the libnl 3.2.25 library was built and installed successfully.

I set a variable manually in the Makefile

NL3xFOUND := Y

and made corrections

CFLAGS += -I/home/lyudmila/timesysMinPoint/twr_vf600/kernel-source/linux-3.13/rfs/include/libnl3
$(info CFLAGS="$(CFLAGS)")
LIBS += -L/home/lyudmila/timesysMinPoint/twr_vf600/kernel-source/linux-3.13/rfs/lib -lnl-3
$(info LIBS="$(LIBS)")

#LIBS += $(shell $(PKG_CONFIG) --libs $(NLLIBNAME))
#CFLAGS += $(shell $(PKG_CONFIG) --cflags $(NLLIBNAME))
endif # NO_PKG_CONFIG

As a result the packet was successfully built.

I have questions to professionals regarding NL3xFOUND := $(shell $(PKG_CONFIG) --atleast-version=3.2 libnl-3.0 && echo Y).

1. Where does this function look for libnl library?

2. What ways for the search does it use in this specific case?

3. Whether can the "shell" in brackets change environment variables?

4.  What is libnl-3.0 in brackets? Is this exact name of libnl library from the /.../kernel-source/linux-3.13/rfs/lib folder or something else?

I am grateful for any help

Hi everybody

I did not understand yet why pkg-config does not function, though PKG_CONFIG_PATH=/home/lyudmila/timesysMinPoint/twr_vf600/kernel-source/linux-3.13/rfs/lib/pkgconfig and the libnl-3.0.pc file is placed in this folder. The pkg-config is installed:

lyudmila@lyudmila-linuxmint ~ $ dpkg -l | grep pkg-config
ii  pkg-config                                  0.29.1-0ubuntu1                              amd64

Very strange situation!!!

I made the following corrections in crda Makefile:

ifeq ($(USE_OPENSSL),1)
#CFLAGS += -DUSE_OPENSSL -DPUBKEY_DIR=\"$(RUNTIME_PUBKEY_DIR)\" `pkg-config --cflags openssl`
CFLAGS += -DUSE_OPENSSL -DPUBKEY_DIR=\"$(RUNTIME_PUBKEY_DIR)\"
#LDLIBS += `pkg-config --libs openssl`
LDLIBS += -lcrypto -lssl

.........

NL3FOUND := Y

...........

    ifeq ($(NL3FOUND),Y)
    CFLAGS += -DCONFIG_LIBNL30
    NLLIBS += -lnl-genl-3 -lnl-3
#    NLLIBS += $(shell pkg-config --libs libnl-genl-3.0)
    NLLIBNAME = libnl-3.0

..................

CFLAGS += -I/home/lyudmila/timesysMinPoint/twr_vf600/kernel-source/linux-3.13/rfs/include/libnl3
#NLLIBS += `pkg-config --libs $(NLLIBNAME)`
#CFLAGS += `pkg-config --cflags $(NLLIBNAME)`

As a result the crda packet was successfully built  and the  execution of the $ ./build_wl18xx.sh update R8.7_SP3  command  came to the end with the message:

Verifying filesystem skeleton...
Wifi Package Build Successful

Still there is not the fs_skeleton.tbz2 file in "<build-utilities>/outputs/" folder.

I looked the  build_wl18xx.sh script.

build_outputs() function  will not create the fs_skeleton.tbz2 file as my ROOTFS =/home/lyudmila/timesysMinPoint/twr_vf600/kernel-source/linux-3.13/rfs

Is it the mistake or so has to be?

build_outputs() function is given below:

function build_outputs()
{
    if [[ "$ROOTFS" == "DEFAULT" ]]
    then  
        echo "Building outputs"
        cd_path filesystem
        tar cpjf `path outputs`/${tar_filesystem[0]} .
        cd_back
        
        # Copy kernel files only if default kernel is used(for now)
        if [[ $DEFAULT_KERNEL -eq 1 ]]
        then
            if [ "$KERNEL_VERSION" -eq 3 ] && [ "$KERNEL_PATCHLEVEL" -eq 2 ]
            then
                cp `path tftp`/uImage `path outputs`/uImage
            else
                if [ -z $NO_DTB ]
                then
                    cp `path tftp`/zImage `path outputs`/zImage
                    cp `path tftp`/*.dtb `path outputs`/
                else
                    cp `path tftp`/uImage `path outputs`/uImage
                fi
            fi
        fi
    fi
}
