| Subject: | Missing `alloca` symbol - help? |
| To: | cygwin AT cygwin DOT com |
I'm not certain this is a problem with Cygwin, but I am unable to find any issue by looking over the project in question, so I thought I'd ask. Is this an obvious bug, either in Cygwin or the project itself? # Steps to reproduce 1. Have the following packages installed (via `cygcheck -c -d`) (asterisk beside packages that I _believe_ are relevant to the issue): Package Version _autorebase 001007-1 alternatives 1.3.30c-10 base-cygwin 3.8-1 base-files 4.2-4 bash 4.4.12-3 binutils 2.29-1 bzip2 1.0.6-3 ca-certificates 2.22-1 coreutils 8.26-2 csih 0.9.11-1 curl 7.59.0-1 cygrunsrv 1.62-1 cygutils 1.4.16-2 cygwin 2.11.1-1 cygwin-devel 2.11.1-1 dash 0.5.9.1-1 dejavu-fonts 2.37-1 desktop-file-utils 0.23-1 diffutils 3.5-2 dos2unix 7.4.0-1 editrights 1.03-1 file 5.32-1 findutils 4.6.0-1 gamin 0.1.10-15 gawk 4.2.1-1 * gcc-core 7.3.0-3 getent 2.18.90-4 git 2.17.0-1 grep 3.0-2 groff 1.22.3-1 gsettings-desktop-schemas 3.24.1-1 gzip 1.8-1 hostname 3.13-1 ImageMagick 6.9.10.11-1 info 6.5-2 ipc-utils 1.0-2 less 530-1 libargp 20110921-3 libatomic1 7.3.0-3 libattr1 2.4.46-1 libautotrace3 0.31.1-19 libblkid1 2.25.2-2 libbz2_1 1.0.6-3 libcairo2 1.14.12-1 libcharset1 1.14-3 libcom_err2 1.42.12-2 libcroco0.6_3 0.6.12-1 libcrypt0 2.1-1 libcurl4 7.59.0-1 libdatrie1 0.2.8-1 libdb5.3 5.3.28-2 libedit0 20130712-1 libEMF1 1.0.9-1 libexpat1 2.2.6-1 libfam0 0.1.10-15 libffi-devel 3.2.1-2 libffi6 3.2.1-2 libfftw3_3 3.3.8-1 libfontconfig-common 2.12.6-1 libfontconfig1 2.12.6-1 libfpx1 1.3.1.4-1 libfreetype6 2.8.1-1 libgcc1 7.3.0-3 libgcrypt-devel 1.8.2-1 libgcrypt20 1.8.2-1 libgdbm4 1.12-1 libgdk_pixbuf2.0_0 2.36.11-1 libgif7 5.1.4-1 libglib2.0_0 2.54.3-1 libgmp10 6.1.2-1 libgomp1 7.3.0-3 libgpg-error-devel 1.28-1 libgpg-error0 1.28-1 libgraphite2_3 1.3.10-1 libgs9 9.25-1 libgssapi_krb5_2 1.15.2-2 libharfbuzz0 1.7.6-1 libICE6 1.0.9-1 libiconv 1.14-3 libiconv-devel 1.14-3 libiconv2 1.14-3 libidn11 1.33-1 libidn2_0 2.0.4-1 libintl8 0.19.8.1-2 libisl13 0.14.1-1 libisl15 0.16.1-1 libjasper4 2.0.14-1 libjbig2 2.0-14 libjpeg-devel 1.5.3-1 libjpeg8 1.5.3-1 libk5crypto3 1.15.2-2 libkrb5_3 1.15.2-2 libkrb5support0 1.15.2-2 liblcms2_2 2.9-1 libltdl7 2.4.6-6 liblzma-devel 5.2.3-1 liblzma5 5.2.3-1 liblzo2_2 2.10-1 libMagickC++6_8 6.9.10.11-1 libMagickCore6_6 6.9.10.11-1 libMagickWand6_6 6.9.10.11-1 libmetalink3 0.1.2-1 libming1 0.4.8-2 libmpc3 1.1.0-1 libmpfr4 3.1.6-1p1 libmpfr6 4.0.1-4p11 libncursesw10 6.0-12.20171125 libnghttp2_14 1.31.0-1 libopenldap2_4_2 2.4.42-1 libopenssl100 1.0.2p-1 libp11-kit0 0.23.10-1 libpango1.0_0 1.40.14-1 libpaper-common 1.1.24-2 libpaper1 1.1.24-2 libpcre1 8.40-3 libpipeline1 1.4.0-1 libpixman1_0 0.34.0-1 libplotter2 2.6-5 libpng16 1.6.34-1 libpopt-common 1.16-2 libpopt0 1.16-2 libpsl5 0.18.0-1 libpstoedit0 3.73-1 libquadmath0 7.3.0-3 libreadline7 7.0.3-3 librsvg2_2 2.40.20-1 libsasl2_3 2.1.26-11 libsigsegv2 2.10-2 libSM6 1.2.2-1 libsmartcols1 2.25.2-2 libsqlite3_0 3.21.0-1 libssh2_1 1.7.0-1 libssp0 6.4.0-4 libstdc++6 7.3.0-3 libtasn1_6 4.13-1 libthai0 0.1.26-1 libtiff6 4.0.9-1 libtool 2.4.6-6 libunistring2 0.9.10-1 libuuid-devel 2.25.2-2 libuuid1 2.25.2-2 libwebp7 0.6.1-2 libwebpmux3 0.6.1-2 libX11_6 1.6.5-1 libXau6 1.0.8-1 libXaw7 1.0.13-1 libxcb-render0 1.12-2 libxcb-shm0 1.12-2 libxcb1 1.12-2 libXdmcp6 1.1.2-1 libXext6 1.3.3-1 libXft2 2.3.2-1 libxml2 2.9.4-2 libxml2-devel 2.9.4-2 libxmlsec1-devel 1.2.24-1 libxmlsec1_1 1.2.24-1 libXmu6 1.1.2-1 libXpm4 3.5.12-1 libXrender1 0.9.9-1 libxslt 1.1.29-1 libxslt-devel 1.1.29-1 libXt6 1.1.5-1 libzip5 1.5.1-1 login 1.12-1 man-db 2.7.6.1-1 mintty 2.9.3-0 ncurses 6.0-12.20171125 openssh 7.8p1-1 openssl 1.0.2p-1 p11-kit 0.23.10-1 p11-kit-trust 0.23.10-1 perl 5.26.2-1 perl-Carp 1.38-2 perl-Error 0.17026-1 perl-Scalar-List-Utils 1.50-1 perl-TermReadKey 2.37-2 perl_autorebase 5.26.2-1 perl_base 5.26.2-1 pkg-config 0.29.1-1 publicsuffix-list-dafsa 20180523-1 python2 2.7.14-1 python2-six 1.10.0-1 * python3 3.6.4-1 python3-appdirs 1.4.3-1 python3-asn1crypto 0.22.0-1 python3-cffi 1.9.1-1 python3-chardet 2.3.0-1 python3-cryptography 1.8.1-1 python3-devel 3.6.4-1 python3-idna 2.5-1 python3-lockfile 0.12.2-1 python3-lxml 3.7.3-1 python3-openssl 16.2.0-1 python3-packaging 16.8-1 * python3-pip 9.0.1-1 python3-ply 3.9-1 python3-pyasn1 0.2.3-1 python3-pycparser 2.17-1 python3-pyparsing 2.1.10-1 python3-requests 2.13.0-1 python3-setuptools 34.3.2-1 python3-six 1.10.0-1 python3-urllib3 1.20-1 python3-wheel 0.30.0a0-1 rebase 4.4.4-1 rsync 3.1.2-1 run 1.3.4-2 sed 4.4-1 shared-mime-info 1.8-1 sqlite3 3.21.0-1 sqlite3-vfslog 3.21.0-1 tar 1.29-1 terminfo 6.0-12.20171125 tig 2.2-1 tzcode 2018e-1 tzdata 2018e-1 util-linux 2.25.2-2 vim 8.0.1567-1 vim-common 8.0.1567-1 vim-minimal 8.0.1567-1 w32api-headers 5.0.4-1 w32api-runtime 5.0.4-1 which 2.20-2 windows-default-manifest 6.4-1 xxd 8.0.1567-1 xz 5.2.3-1 zlib 1.2.11-1 zlib-devel 1.2.11-1 zlib0 1.2.11-1 2. Run `pip install cmarkgfm==0.2.0` # Expected result Install cmarkgfm package # Observed result Fails to install. Particularly, the error output makes multiple mentions of `undefined reference to `alloca'` during linking (full error log at https://github.com/theacodes/cmarkgfm/issues/13). # Notes As far as I can tell, `alloca` is a standard Unix function (though deprecated). Also, in Cygwin, `/usr/includes/alloca/h` exists, suggesting the function _should_ exist to be linked without further packages? That's the extent of what I've been able to glean. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
