I want to use Luacpp in an SGX application. For example, in the SampleEnclave application, I want to send some Lua codes to be executed securely in SGX.
I have updated the Enclave's MakeFile to make the SampleEnclave app Lua compatible. But getting below error:

Can I get rid of the dynamic library dependency from LUA? Because SGX does not support dynamic libraries in Enclave.

I am using gcc10 for my code. My system installed the official libraries compiled by gcc11.
OS：archlinux
compiler: gcc-10
Archlinux updated their official compiler to gcc-11.
When I use gcc10 to compile my code and link to the libraries compiled by gcc11, it shows the following error message:
/usr/bin/ld: /usr/lib/libQt5Core.so.5.15.2: undefined reference to `std::__exception_ptr::exception_ptr::_M_release()#CXXABI_1.3.13'
/usr/bin/ld: /usr/lib/libQt5Widgets.so.5.15.2: undefined reference to `std::__throw_bad_array_new_length()#GLIBCXX_3.4.29'
/usr/bin/ld: /usr/lib/libQt5Core.so.5.15.2: undefined reference to `std::__exception_ptr::exception_ptr::_M_addref()#CXXABI_1.3.13'
It seems related to stdc++ libraries. What should I do?
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
I tried to use gcc11 to compile everything including the libraries. It is fine to compile the libraries that I need.
When I compile my code, it shows the error messages:

Is it related to stdc++ lib? or my compiler? I think my code is fine because I can compile it on my old machine (archlinux but the compiler is gcc10).
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
I can't uninstall gcc10 because I am using CUDA11 which depends on gcc10.
I'm trying to install the libpca package.
I've already have Armadillo set up.
The libpca package is unzipped to /my/dir/. And I set the CPLUS_INCLUDE_PATH and other variables to the place Armadillo installed. (export CPLUS_INCLUDE_PATH=/my/dir/arma_install/include/:$CPLUS_INCLUDE_PATH)
I run the following command to install libpca:
/my/dir/libpca-1.3.3$ ./configure --prefix=/my/dir/libpca-1.3.3
/my/dir/libpca-1.3.3$ make
which has warnings but no error. And the command:
/my/dir/libpca-1.3.3$ make install prefix=/my/dir/libpca-1.3.3
It seems good and no error is reported.
Then I try to compile and run the example file in /my/dir/libpca-1.3.3/examples/simple/pca_example.cpp. In dir examples, I run
/my/dir/libpca-1.3.3/examples$ make
It returns
make[1]: Nothing to be done for 'all'
make[1]: Nothing to be done for 'all-am'
And no new file is created. Then I cd into examples/simple, and run
/my/dir/libpca-1.3.3/examples/simple$ make
It returns:
make: Nothing to be done for 'all'
And no new file is created. Then I run
/my/dir/libpca-1.3.3/examples/simple$ make check
It returns the following errors:
The variables wrapper_dsyev_, wrapper_dgemv_, wrapper_dgemm_, etc. in the errors above, exist in the following binaries:
/my/dir/arma_install/lib64/libarmadillo.so.8.500.0
/my/dir/arma_downloaded/CMakeFiles/armadillo.dir/src/wrapper.cpp.o
/my/dir/arma_downloaded/CMakeFiles/CMakeRelink.dir/libarmadillo.so.8.500.0
After I export them into LD_LIBRARY_PATH, the same errors are still returned.
I think there should be something wrong with the include path, and environment variables. How do I solve it?
Moreover, if I need to write code in /my/dir/working_dir/, how can I set the path?
----------------------------------edited below--------------------
When I made the update described below, at step 3:
/my/dir/libpca-1.3.3$ LD_LIBRARY_PATH=/my/dir/arma_install/lib64 make check
It returns the following errors:

What should I do next?
You need to tell the linker of the location of your armadillo library. You can achieve this in two ways:
Through environment variable: export LIBRARY_PATH=/arma/lib:$LIBRARY_PATH
Passing armadillo include and library path to configure directly:
./configure --with-armadillo-incdir=/arma/include --with-armadillo-libdir=/arma/lib
I would recommend using option 2 as it prevents settings up extra environment variables which may pollute, well, your environment.
Note that --prefix denotes the directory in which libpca is being installed to. This should be different from the source directory!
After configure you can run make, make check, and make install. For make check to succeed the linux library loader needs to know the location of the armadillo shared library. So one option is to run like so: LD_LIBRARY_PATH=/arma/lib make check
To summarize the commands you need to run:
./configure --prefix=/libpca/install --with-armadillo-incdir=/arma/include --with-armadillo-libdir=/arma/lib
make
LD_LIBRARY_PATH=/arma/lib make check
make install
Obviously, you need to adjust the paths to your situation.
Caveat: On some platforms you need to explicitly link with lapack and blas. So if you run into further linker errors then try configuring like this:
LIBS='-llapack -lblas' ./configure --prefix=/libpca/install --with-armadillo-incdir=/arma/include --with-armadillo-libdir=/arma/lib
I encounter the following linking error when attempting to use in Cygwin64. My PATH accounts for the location of libbz2.a and libbz2.dll.

FYI, I've already installed freeglut, libgtk and libwxgtk.
I'm trying to compile the DumpFile example on Raspbian using the arduino-core and arduino-mk packages.
It usually worked well for other projects, but when it comes to using the SD library I have errors at compilation time, I don't know if it's something I do wrong or if it's an issue in the SD library itself.
From the changelog of the arduino-core package, there are nothing that was fixed in the SD library between my version of the package and the most recent one. So upgrading may not help.
I'm copying the output of running >make

Could someone please help me to pinpoint at the issue?
Thanks
Note the SD library has a sub directory containing the functions that are undefined. Perhaps you need to add -I/usr/share/arduino/libraries/SD/utility to your make
