Boost issue compiling on Red Hat 8 with system gcc/8.3.1

[justbennet]

We recently tried to install Boost 1_78_0 on our Red Hat 8.3 system, which has GCC 8.3.1. Red Hat has 'hardened' their installation of GCC such that the precompiled headers generate errors. We also tried this on an system that was updated to Red Hat 8.5, which provides GCC 8.5.0 with comparable results.

Is there a configuration flag we can give to disable use of precompiled headers?

I am using

$ ./bootstrap.sh --prefix=/tmp/local
$ ./b2 --prefix=/tmp/bennetsw/local

and I get errors that look like these.

gcc.compile.c++ bin.v2/libs/math/build/gcc-8/release/threading-multi/visibility-hidden/acosh.o

I did not see anything in the help for either bootstrap.sh or for b2 that looks like it would address this. Any help would be appreciated.

A colleague found the option to suppress use of precompiled headers. For anyone else who might be looking, this seems to work. After running the usual bootstrap.sh command to configure b2, use

./b2 --prefix=${PREFIX} --build-dir=${BUILD_DIR} pch=off ${CONFIG_OPTIONS}
./b2 --prefix=${PREFIX} --build-dir=${BUILD_DIR} pch=off ${CONFIG_OPTIONS} install

where ${CONFIG_OPTIONS} are any other options passed to b2.

It may be obvious to most people, but it was not obvious to us that the pch=off option needs to be on both the build and install.
