./configure fails on osx due to empty else statements #3471

Works fine after deleting 'else' lines in 3(?) places where else block was empty... otherwise fails with 'unexpected "fi"' error

trunk 6e7792003b5c520fcc81d223f07471d690594081

You'll need to provide more of the code around the "else" lines. Official releases don't have any empty else blocks.

I'm encountering this problem using MinGW running on Windows 7. Here are the statements in configure.ac that I think are causing the problem:

#if BOOST_VERSION >= 105000 && (!defined(BOOST_HAS_NANOSLEEP) || BOOST_VERSION >= 105200) boost::this_thread::sleep_for(boost::chrono::milliseconds(0)); #else choke me #endif

#if BOOST_VERSION <= 105600 boost::this_thread::sleep(boost::posix_time::milliseconds(0)); #else choke me #endif

Command: BOOST_ROOT=~/boost_1_55_0 CPPFLAGS="-D_WIN32_WINNT=0x0602 -DWINVER=0x0602" sh configure --enable-wallet=no --enable-tests=no

Error: configure: line 9740: syntax error near unexpected token fi' configure: line 9740:fi'

Lines causing error in configure: _ACEOF if ac_fn_cxx_try_compile "$LINENO"; then :

    { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5

$as_echo "yes" >&6; } succeeded=yes found_system=yes

else

fi

_ACEOF if ac_fn_cxx_try_compile "$LINENO"; then :

        { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5

$as_echo "yes" >&6; } succeeded=yes found_system=yes

else

fi

Commenting out the two 'else' statements results in the following when running the script:

checking for boostlib >= 1.20.0... configure: We will use a staged boost library from /home/rwh/boos t_1_55_0 yes checking whether the Boost::System library is available... yes checking for exit in -lboost_system-mgw48-sd-1_55... yes checking whether the Boost::Filesystem library is available... yes checking for exit in -lboost_filesystem-mgw48-sd-1_55... yes checking whether the Boost::Program_Options library is available... yes checking for exit in -lboost_program_options-mgw48-1_55... yes checking whether the Boost::Thread library is available... yes checking for exit in -lboost_thread-mgw48-mt-sd-1_55... yes checking whether the Boost::Chrono library is available... yes checking for exit in -lboost_chrono-mgw48-1_55... yes

Running 'make' is successful and both bitcoind and bitcoin-cli work correctly.

The configure script that is generated here does not contain the empty else clause at all:

if ac_fn_cxx_try_compile "$LINENO"; then :

        { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5
$as_echo "yes" >&6; }
    succeeded=yes
    found_system=yes

fi

May be an autoconf/automake version issue

$ autoconf --version
autoconf (GNU Autoconf) 2.68
$ automake --version
automake (GNU automake) 1.11.3

Ronald Hoffman@Hoffman-Gaming ~
$ autoconf --version
autoconf (GNU Autoconf) 2.68
Ronald Hoffman@Hoffman-Gaming ~
$ automake --version
automake (GNU automake) 1.11.1

so virtually the same ... weird. configure is generated from configure.ac and I don't see any strange empty clauses there..

#3752 should solve this, can anyone help testing please?

Problem fixed by #3752

confirmed: wilbown's commit 5d5b0d284a787fc9a3c53c59232ebc2c09dffaeb fixed the problem for me. Thank you.

Any chance you can undelete MtGox, too?

Welcome, I feel special. Working on the Gox issue now :-P
