Unable to build on Mac OS Mojave about libcaes

[Trent54]

Oops, forgot to attach output of make

[joachimmetz]

how did you get the source via git or from the source distribution package ?

Can you attach your config.log

[Trent54]

Hi Joachim, thank you for getting back to me. I got it from Git but when I run ./synclibs.sh, per the instructions here: I get the following error:

@Trent54 it looks like your previous message did not contain all the data, don't use the reply via email option it has limitations.

You are running the development version as explained here https://github.com/libyal/libcaes/wiki/Building#read-first
If you're not developing libcaes or libfsapfs, then I opt to not use this version.

(I repeat) can you attach your config.log

[Trent54]

It is attached. Thank you again!

It is not, since you did use reply via email again

Per the github reply "it looks like your previous message did not contain all the data, don't use the reply via email option it has limitations."

[Trent54]

I understand now, sorry - reply via Github incoming

config.log

[joachimmetz]

libcaes/libcaes/libcaes_context.c

Line 324 in 8fe8e46

#elif defined( HAVE_LIBCRYPTO ) && defined( HAVE_OPENSSL_EVP_H ) && ( defined( HAVE_EVP_CRYPTO_AES_CBC ) || defined( HAVE_EVP_CRYPTO_AES_ECB ) )

#elif defined( HAVE_LIBCRYPTO ) && defined( HAVE_OPENSSL_EVP_H ) && ( defined( HAVE_EVP_CRYPTO_AES_CBC ) || defined( HAVE_EVP_CRYPTO_AES_ECB ) )

Per config.log

| #define HAVE_OPENSSL_EVP_H 1
| #define HAVE_LIBCRYPTO 1
| #define HAVE_OPENSSL_AES_H 1
...
ac_cv_libcrypto=yes
ac_cv_libcrypto_CPPFLAGS=-I/opt/local/include
ac_cv_libcrypto_LIBADD=-lcrypto
ac_cv_libcrypto_aes=no
ac_cv_libcrypto_aes_cbc=no
ac_cv_libcrypto_aes_ecb=no
ac_cv_libcrypto_aes_xts=no
ac_cv_libcrypto_dummy=no
ac_cv_libcrypto_evp=yes
ac_cv_libcrypto_evp_cipher=no

But the following are missing:

HAVE_AES_CBC_ENCRYPT
HAVE_AES_ECB_ENCRYPT
HAVE_EVP_CRYPTO_AES_CBC
HAVE_EVP_CRYPTO_AES_ECB

So LIBCAES_HAVE_AES_SUPPORT is not set in

libcaes/libcaes/libcaes_definitions.h.in

Line 56 in 0459d83

#elif defined( HAVE_LIBCRYPTO ) && defined( HAVE_OPENSSL_EVP_H )

since both HAVE_LIBCRYPTO and HAVE_OPENSSL_EVP_H are set but your OpenSSL build does not appear to have the EVP Cypher functions.

I'll have a look to change m4/libcrypto.m4 to account for this case in the mean time run configure with --with-openssl=no to disable OpenSSL support.

[Trent54]

Awesome, I'll give it a try now. Thank you!

[joachimmetz]

Or this might be related to your build environment not properly configured:

ld: library not found for -lcrypto
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Try setting (or equivalent that corresponds with your system):

export CFLAGS="-I/usr/local/include -I/usr/local/opt/[email protected]/include ${CFLAGS}";
export LDFLAGS="-L/usr/local/lib -L/usr/local/opt/[email protected]/lib ${LDFLAGS}";

before running ./configure

[Trent54]

Hmmm...

Was getting another error with before (see below) but will try that way

[Trent54]

Still same error after setting CFLAGS & LDFLAGS per above.

[joachimmetz]

You'll need to run ./synclibs.sh and ./autogen.sh as indicated here https://github.com/libyal/libcaes/wiki/Building#git

I repeat using the source from git is NOT recommended if you're not developing libcaes.

[Trent54]

Here is an ls of my libcerror directory

[Trent54]

I tried following directions, really :) I did that but had an error.

[Trent54]

This error:

[joachimmetz]

Why is that an error?

[Trent54]

It isn't?

[Trent54]

I thought it was because reinstalling libcaes didn't fix the original problem. (attached).

[Trent54]

I also installed liberror separately - I'm guessing I shouldn't have done that because there is a libcerror directory inside libcaes and one in the git directory

[joachimmetz]

You are not listening to my advise nor are you following the instructions that have been written to prevent people falling in to the trap of trying to use the version that is intended for development only.

1. Stop using the source from git directly.
2. Use https://github.com/libyal/libfsapfs/releases/download/20200416/libfsapfs-experimental-20200416.tar.gz

It has all the dependencies included. Use --with-openssl=no or make sure to set up CFLAGS & LDFLAGS as indicated before.

[Trent54]

I am sorry, I am new to using git.

[Trent54]

I will build from inside the .tar.gz which I have downloaded. I didn't understand which part of your directions applied to what. I remember I started with Mac OS build from package, then after that failed I found the build from source directions.

[Trent54]

I see now. This is more to my unfamiliarity with git I think. I found an article about libfsapfs, searched and found the project on git, clicked documentation and clicked "build from source." I actually thought that's all anyone could use GitHub for and did not understand the concept of separate releases.

I don't mean to imply the documentation does not make this clear. Thank you again for all your help.
