使用 gcc 3.4.5 编译 TCL 7.6.2
我正在使用 gcc 3.4.5 编译 TCL 7.6p2。我使用的是 CentOS 5.5。我在 make 命令期间收到以下错误：
./../generic/tclPosixStr.c: In function `Tcl_ErrnoId':
./../generic/tclPosixStr.c:340: error: duplicate case value
./../generic/tclPosixStr.c:328: error: previously used here
./../generic/tclPosixStr.c: In function `Tcl_ErrnoMsg':
./../generic/tclPosixStr.c:787: error: duplicate case value
./../generic/tclPosixStr.c:775: error: previously used here
make: *** [tclPosixStr.o] Error 1
任何提示将不胜感激。谢谢。

您正在尝试使用多年来一直不受支持的古老版本。因此，最好的方法是破解源代码，从这些
switch语句中注释掉有问题的情况。 或者切换到有人愿意支持的东西（但这是你的决定）。详细来说： 看起来 EOPNOTSUPP 与 ENOTSUP 的值相同；注释掉与 EOPNOTSUPP 关联的每组三行（或至少带有
case的行；周围的#ifdef机制无害），以使问题消失。或者，您可以向后移植所有非上古版本中存在的更改，即将#ifdef行改进为：不过，不必将其报告为错误。 不支持 Tcl 7.6p2。
You're trying to use an ancient version that's not been supported for many many years. As such, your best approach is to hack the source code to comment out the offending cases from those
switchstatements. Or switch to something that someone can be bothered to support (but that's your call).In detail: It appears that EOPNOTSUPP is the same value as ENOTSUP; comment out each group of three lines (or at least the lines with the
case; the surrounding#ifdefmachinery isn't harmful) associated with EOPNOTSUPP to make the problem go away. Or you can backport the change that's present in all non-antediluvian versions, which is to improve the#ifdeflines to this:Don't bother reporting this as a bug though. Tcl 7.6p2 is not supported.
