Compiling error with glmnet and nloptr

Just a note that I used R 4.1.2 and with R 4.1.3 I had the same issues nevertheless I was able to go through with (not entirely sure preferable) nloptr once abs() is changed into fabs() within ?src/test-C-API.cpp. Thanks. Jing Hua

Dear All,

I haven't been able to compile the latest glmnet and nloptr from CRAN wth the following error messages,

glmnet:

elnet_exp.cpp:141:59:   required from here
glmnetpp/include/glmnetpp_bits/elnet_point/gaussian_base.hpp:90:39: error: 'self' was not declared in this scope
                     [=](auto k) { self().template update<update_type::partial>(k, ab, dem); },
...
make: *** [elnet_exp.o] Error 1
ERROR: compilation failed for package ?glmnet?
* removing ?/rds/user/jhz22/hpc-work/R/glmnet?
* restoring previous ?/rds/user/jhz22/hpc-work/R/glmnet?

nloptr:

test-C-API.cpp:108:35: error: call of overloaded 'abs(__gnu_cxx::__alloc_traits<std::allocator<double> >::value_type)' is ambiguous
     expect_true(abs(res[1] - 8./27) < 1.0e-4);

   abs(long __i) { return __builtin_labs(__i); }
   ^~~
make: *** [test-C-API.o] Error 1
ERROR: compilation failed for package ?nloptr?

Any suggestions to fix these? I use gcc/6 and have

$ uname -a
Linux login-e-16 3.10.0-1160.59.1.el7.x86_64 #1 SMP Tue Feb 22 10:57:56 CST 2022 x86_64 x86_64 x86_64 GNU/Linux

Many thanks in advance,
