Compilation of relic fails with “size of array element is not a multiple of its alignment”

[gnull]

I was trying to compile the current ENCRYPTO_utils master (331c22f) and got this error while compiling relic.

To reproduce the error, I ran

mkdir build
cd build
cmake ..
make

from the project root.

Interestingly, if I

1. upgrade to the latest version of relic by

   cd extern/relic
   git checkout main
   git pull
   

2. and then comment out the lines

   ENCRYPTO_utils/CMakeLists.txt

   Lines 34 to 53 in 331c22f

   	set(DEBUG off CACHE BOOL "Build relic with debugging support")
   	set(PROFL off CACHE BOOL "Build relic with profiling support")
   	set(CHECK off CACHE BOOL "Build relic with error-checking support")
   	set(ALIGN "16" CACHE STRING "Relic align")
   	set(ARCH "X64" CACHE STRING "Architecture to be used in relic")

   	set(FB_SQRTF off CACHE BOOL "sqrtf for relic")
   	set(EB_METHD "PROJC;LODAH;COMBS;INTER" CACHE STRING "Methods for eb in relic")

   	set(SHLIB off CACHE BOOL "Relic shared library")
   	set(STLIB on CACHE BOOL "Relic static library")

   in CMakeLists.txt,

the compilation succeeds.

Hope this helps.

Also, if I only upgrade relic to main but don't comment out the mentioned lines, I get a “target specific option mismatch” error. It could be related to relic-toolkit/relic#177.

But I'm almost sure this isn't a relic bug, because I can compile relic with cmake .. && make on my machine. Could something be wrong with the compile options that ENCRYPTO_utils uses to build relic?

This problem is known and fixed with recent relic commits: relic-toolkit/relic#202
Please consider updating the relic submodule.

I am facing the same problem in another project (OTExtension) that depends on this project.
It is failing in the same place while compiling relic.
Any chance of updating the relic dependency in this project, otherwise building this project and other dependent projects would need workaround in the build scrips
