Dovecot installation problem (libssl_iostream_openssl.so is not portable!)

Hi there,

i try to install dovecot from source with the following configuration:

./configure --prefix=/test/core/dovecot --with-ssldir=/test/core/dovecot/tls

the configuration runs fine with the following output at the end:

Install prefix . : /test/core/dovecot File offsets ... : 64bit I/O polling .... : epoll I/O notifys .... : inotify SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file shadow checkpassword : -pam -bsdauth -ldap -sql userdbs ........ : static prefetch passwd passwd-file checkpassword : -ldap -sql CFLAGS ......... : -std=gnu99 -g -O2 -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/test/dep/openssl/include SYSTEMD ........ : notify - /lib/systemd/system/dovecot.service SQL drivers .... : : -pgsql -mysql -sqlite -cassandra Full text search : squat : -lucene -solr

But when i start to build (make) after a while i get the following error:

*** Warning: Linking the executable test-iostream-ssl against the loadable module *** libssl_iostream_openssl.so is not portable! libtool: link: gcc -std=gnu99 -g -O2 -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/test/dep/openssl/include -o .libs/test-iostream-ssl test-iostream-ssl.o ./.libs/libssl_iostream_openssl.so ./.libs/libssl_iostream.a ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a -L/test/dep/openssl/lib64 -lssl -lcrypto -ldl -Wl,-rpath -Wl,/test/core/dovecot/lib/dovecot /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to ERR_free_strings' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to ENGINE_cleanup' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to SSL_library_init' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to OBJ_cleanup' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to CRYPTO_cleanup_all_ex_data' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to OpenSSL_add_all_algorithms' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to SSL_CTX_set_tmp_rsa_callback' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to EVP_cleanup' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to SSL_load_error_strings' /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to SSL_CTX_need_tmp_RSA' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:655: test-iostream-ssl] Error 1 make[3]: Leaving directory '/test/tmp/dovecot-2.3.17.1/src/lib-ssl-iostream' make[2]: *** [Makefile:573: all-recursive] Error 1 make[2]: Leaving directory '/test/tmp/dovecot-2.3.17.1/src' make[1]: *** [Makefile:702: all-recursive] Error 1 make[1]: Leaving directory '/test/tmp/dovecot-2.3.17.1' make: *** [Makefile:546: all] Error 2

I've searched for the error and find some posts about set explicitly CPPFLAGS and LDFLAGS and something about missing shared libraries of openssl.

My openssl have shared libraries (libcrypto.so libssl.so ...) and the explicit use of CPPFLAGS and LDFLAGS to my openssl hasn't changed anything

I use Openssl 3.0 but i've tested also 1.1.1m and 1.1.1g for example, same error! Dovecot is the latest 2.3.17.1 My OS is Ubuntu 21.04

Can anyone help me with this please? Thanks!
