(SOLVED) Error compiling ZM1.25 in ARM based computer

[PacoLM]

Hello,

I just tried to install ZM1.25 in one of my guruplugs. I have some problems when running the make command. This is the configure command:

Code: Select all

export CFLAGS="-march=native -O2 -pipe" && \
export CXXFLAGS="${CFLAGS}" && \
export CPPFLAGS="${CFLAGS}"
./configure --with-webdir=/var/www/zm --with-cgidir=/usr/lib/cgi-bin \
ZM_DB_HOST=localhost ZM_DB_NAME=zm ZM_DB_USER=zmuser \
ZM_DB_PASS=zmpass ZM_SSL_LIB=openssl --enable-debug=no \
--with-webgroup=www-data --with-webuser=www-data --enable-mmap=yes CPPFLAGS="-D__STDC_CONSTANT_MACROS ${CPPFLAGS}"

I have an error when compiling zm_signal.cpp:

Code: Select all

zm_signal.cpp: In function ‘void zm_die_handler(int, sigcontext)’:
zm_signal.cpp:91:2: error: ‘struct sigcontext’ has no member named ‘cr2’
make[2]: *** [zm_signal.o] Error 1
make[2]: Leaving directory `/usr/src/zm/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/src/zm'

Is there anything wrong in the configuration parameters? I have googled looking for the error and seems related to the registers (page fault register indeed), could anyone confirm this?
If so, which registers should I put instead of the cr2 (i386) register?. Is there any configuration to compile the package for armel architectures to avoid this error?.

Thanks in advance,

PacoLM

I've done a bunch of reading and have come to the conclusion I can't definitively help you! But a major difference between RISC and x386 based processors is how they handle memory. Because I know you've had this running on sub releases (thanks for your posts) I'm going to suggest an experimental build with mmap=no. Relatively new to ZM, mmap may be causing your register issues; just a WAG but in looking at the different CRx values I can't suggest a better one (maybe 0).

Hi,

I have compared the file zm_signal.cpp of the version 1.24.4 and the registers are the same, so I believe the source of the problem is not the register name. As suggested by another forum user, I need to check the compilation parameters and compiler versions.

Thanks,

Hi,

Fixed with the help of my friend Paco Gil:

Well the fix turned out to be changing cr2 to fault_address in zm_signal.cpp. I forgot where I got that solution from but it compiles without problem now.

Now I'm reinstalling the complete OS, I did too many dirty things on the guruplug and only to have Zoneminder working it's 89% full.

Hope it helps,
