Arm64 Build

[Bab95]

I am building tpm2-tss repo on Arm64 arch ubuntu20.04 machine and facing missing openssl error while running configure command.
I have build openssl 3.2.0 on the same machine and added path as well as defined in LDFLAGS and CFLAGS.
Following are the flags and values i have configured.

babnishvyas@bab-arm-linux:/usr/src/tpm2-tss$ curl -V

I am not sure what am I missing here. is there any problem in building it on arm64?

[joholl]

For ./configure to be happy, pkg-config must find your library. It is not sufficient to set the LDFLAGS. If pkg-config finds your .pc file, it will tell the LDFLAGS/CFLAGS to automake, anyway.

If you installed openssl via dpkg/apt, see #2866 (comment).

If you installed openssl manually (i.e. not via dpkg/apt), you might need to change your install location or set PKG_CONFIG_PATH to make pkg-config find the .pc file (which is generated in the openssl build step)

[Bab95]

defining PKG_CONFIG_PATH doesn't make any difference, Issue is still the same.

[Bab95]

Manually providing the CRYPTO_LIBS and other flags resolve the above issue but still causing problems in make command.

./configure CRYPTO_LIBS=-L/usr/local/arm64/openssl/lib CRYPTO_CFLAGS=-I/usr/local/arm64/openssl/include CURL_LIBS=-L/usr/local/arm64/curl/lib CURL_CFLAGS=-I/usr/local/arm64/curl/include

To all the people who struggled out there following command worked
./configure CRYPTO_LIBS="-L/usr/local/arm64/openssl/lib -lssl -lcrypto" CRYPTO_CFLAGS="-I/usr/local/arm64/openssl/include" CURL_LIBS="-L/usr/local/arm64/curl/lib -lcurl" CURL_CFLAGS="-I/usr/local/arm64/curl/include" CFLAGS="-I/usr/local/arm64/openssl/include"

probably CRYPTO_CFLAGS could be dropped. I don't know haven't checked. but i would still like to know why pkg-config didn't work and why i had to define CRYPTO_LIBS flag and CURL_LIBS flag specifically forcing to find libs not even LDFLAGS setting was enough. If this is going to be the case then probably build instructions need to be updated.
Weird combination of flags though linking done via specific flags and include needs to be set with CFLAGS
