两个静态库重复定义造成冲突如何解决？
编译器：SimplyFortran 3.31Dislin库文件dismg_d.a与SimplyFortran自带界面库文件libappgraphics.a中均有line子程序，重复定义造成冲突
报错信息：

use module 的时候，只导出需要的函数， use A,only: B. 如果两个line都需要，可以用别名use A, AB=>B li913 发表于 2023-9-23 12:12

这俩库如果有源代码还好，可以改一下。
如果没有源代码，还是比较麻烦的。

改别名试过了，不行 DISLIN: (LINE) -> (STRTPT, STRTPT)
or
SimplyFortran, AppGraphics: (line) -> (moveto, lineto)
======================================================================
DISLIN: (LINE) -> (STRTPT, STRTPT)
======================================================================
L I N E
LINE joins two points with a line.
Different line styles can be used.
The call is: CALL LINE (X1, Y1, X2, Y2) level 1, 2, 3
X1, Y1are real numbers containing the plot coordinates of the first point.
X2, Y2are real numbers containing the plot coordinates of the second point.
----------------------------------------
XMOVE and XDRAW are simple subroutines for plotting lines.
Different line styles can be used.
The calls are:CALL STRTPT (X, Y) level 1, 2, 3
CALL CONNPT (X, Y) level 1, 2, 3
X, Y are real numbers containing the plot coordinates.

SimplyFortran, AppGraphics: (line) -> (moveto, lineto)
======================================================================
line
Fortran subroutine line (x1, y1, x2, y2)
Description
Draws a line using the current color from point (x1,y1) to point (x2,y2).
Parameters
Parameter Fortran Type Description
x1 integer Horizontal coordinate of the start point of the line
y1 integer Vertical coordinate of the start point of the line
x2 integer Horizontal coordinate of the end point of the line
y2 integer Vertical coordinate of the end point of the line
----------------------------------------
moveto
Fortran subroutine moveto (x, y)
Description
Sets the current position to be used with subsequent relative graphics operations.
Parameters
Parameter Fortran Type Description
x integer Horizontal coordinate of the current position
y integer Vertical coordinate of the current position
--------------------
lineto
Fortran subroutine lineto (x, y)
Description
Draws a line from the current position to the point (x, y) using the current color.
The current position is moved to this new offset after the drawing operation.
Parameters
Parameter Fortran Type Description
x integer Horizontal coordinate of the end point of the line
y integer Vertical coordinate of the end point of the line

用相同功能函数代替还是不行 weixing1531 发表于 2023-9-25 10:03

請告知 "錯誤訊息" chiangtp 发表于 2023-9-25 10:13
請告知 "錯誤訊息"
还是相同的错误信息，网上说只有对静态库进行重新改名封装了 1. "LINE" 在DISLIN中為"EXTERNAL" subroutine,在AppGraphics中應該也是
2. 如果都是"MODULE" subroutines, li913的作法OK
3. 如果 錯誤訊息 仍是 multiple definition of `line', 請確認:你的程式中 所有的 "LINE"calls 均已做替換
DISLIN: (LINE) -> (STRTPT, CONNPT)
AppGraphics: (line) -> (moveto, lineto) 这是SF作者的答复：错误是由链接器而非编译器产生的。链接器遇到两个不同的行过程并失败。即使您没有显式地使用line，由于库中的一些较低级别调用，它仍然很有可能需要链接。
