Cargo: make error: "could not read symbols", "-fPIC"

[liigo]

after ./configure && make, I got this link error:

This looks like it's linking statically against OpenSSL which wasn't compiled with -fPIC, how is OpenSSL installed on your system?

[liigo]

I compiled openssl myself, just ./config && make && make install, some times ago. Debian 7.x 64bit.
I'll try to compile it with -fPIC, and report result here.

@alexcrichton
I have made sure that my openssl was re-compiled with -fPIC (include rsaz_exp.o).
But when compiling cargo I still got a similar error:

note: /usr/bin/ld: /home/liigo/rust/cargo/target/x86_64-unknown-linux-gnu/deps/liblibgit2-fcba23a36b59f31c.rlib(r-crypto-rsaz_exp.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

collect2: error: ld returned 1 exit status

error: aborting due to previous error
Could not compile `cargo`.

How I compile openssl:

git clone git://git.openssl.org/openssl.git
cd openssl
./config -fPIC --prefix=/usr/local --openssldir=/usr/local/ssl
make
make install

It is compiled as static library. (And was already linked to non-Rust project, it works.)

How I compile cargo:

make clean
./configure
make

followed by rm -rf ~/.cargo.

Thank you @alexcrichton ! The problem is solved (after a clean cargo make).

Recompile openssl with -fPIC is the key:
./config -fPIC --prefix=/usr/local --openssldir=/usr/local/ssl
