# The pre-compiled PhantomJS binary used in this package dates from 2014 and is
# linked to use libcrypto.so and libssl.so from OpenSSL 1.0, but does not
# specify their version (e.g. libcrypto.so.1.0.0). Hence, running PhantomJS
# crashes (segmentation fault) on systems with OpenSSL 1.1 installed, because
# libcrypto.so and libssl.so refer to the new version 1.1. Removing
# /lib64/libssl.so from the system removes the crash, but of course it's not a
# real fix. I've tried multiple solutions including using LD_PRELOAD or
# patchelf, but the only working I've found is to alter PhantomJS binary to make
# it fail loading libcrypto.so and libssl.so. This is it:
# cryptooffset=$((0x01ca2c53)) # 30026835, 1.9.7
cryptooffset=$((0x01ca2d53))
test "$(dd if=bin/%{name} bs=1 skip=$cryptooffset count=6 status=none)" = "crypto" && \
printf "xxxxxx" | dd of=bin/%{name} bs=1 seek=$cryptooffset count=6 conv=notrunc
