Hi,<br>
The errors are due to fortify not been part of build script, either add<br>
lssp to build or set fortify level as zero , sample script modifications<br>
<br>
modify build.sh script from line number 762-765 as shown below<br>
*original :*<br>
cppflags="-D_FORTIFY_SOURCE=2"<br>
cflags="-O2 -g -mms-bitfields -fexceptions -ftree-vectorize ${arch_cflags}"<br>
cxxflags="${cflags}"<br>
ldflags="-static-libgcc -Wl,--enable-auto-image-base -Wl,--dynamicbase<br>
-Wl,--nxcompat"<br>
<br>
*modified:*<br>
cppflags="-D_FORTIFY_SOURCE=0"<br>
cflags="-O2 -g -mms-bitfields -fexceptions -ftree-vectorize ${arch_cflags}"<br>
cxxflags="${cflags}"<br>
ldflags="-static-libgcc -Wl,--enable-auto-image-base -Wl,--nxcompat"<br>
<br>
It can solve those build errors, but please review them as per their<br>
documentation.<br>
<br>
